Concept Introduction
The slope of a line:
The slope of a line represents the change in the value of y-axis per unit value on the x-axis. The slope of a line is a measure of the steepness of the line.
Expert Solution & Answer
Explanation of Solution
(a) If the price of movies increases, fewer consumers go to see movies.
- Panel (a) matches the given statements because as the price of the movies will increase, the number of fans going to movies will decrease.
- The variable ‘price of movies’ shall appear on the vertical axis and the variable ‘number of fans’ will appear on the horizontal axis.
- As the variable on the vertical axis increases, the variable on the horizontal axis will decrease. Thus, there is a negative relationship between the two variables indicating the slope is negative. The curve is Concave or decreasing.
Conclusion:
Thus, the slope is negative.
(b) More experienced workers typically have higher incomes than less experienced workers.
- Panel (c) matches the given statements because as the experience of a worker increases, the income will also increase.
- The variable ‘experience of workers’ shall appear on the vertical axis and the variable ‘income of workers’ will appear on the horizontal axis.
- As the variable on the vertical axis increases, the variable on the horizontal axis will also increase. Thus, there is a positive relationship between the two variables indicating that the slope is positive. It is a convex curve or increasing.
Conclusion:
Thus, the slope is positive.
(c) Whatever is the temperature outside, people consume the same number of hot dogs per day.
- Panel (d) matches the given statements because whatever is the outside temperature, the hot dog consumption remains the same.
- The variable ‘temperature’ shall appear on the horizontal axis and the variable ‘consumption of hot dogs’ shall appear on the vertical axis.
- Even if the variable on the horizontal axis increases, the variable on the vertical axis will remain the same. Thus, there is no relationship between the two variables indicating that the slope is zero.
Conclusion:
Thus, the slope is zero.
(d) Consumers buy more frozen yogurt when the price of ice cream goes up.
- Panel (c) matches the given statement because as the price of ice cream increases, the sale of frozen yogurt also increases.
- The variable ‘price of ice cream’ shall appear on the vertical axis and the variable ‘sale of frozen yogurt’ will appear on the horizontal axis.
- As the variable on the vertical axis increases, the variable on the horizontal axis will also increase. Thus, there is a positive relationship between the two variables indicating that the slope is positive.
Conclusion:
Thus, the slope is positive.
(e) Research finds no relationship between the number of diet books purchased and the number of pounds lost by the average dieter.
- Panel (d) matches the given statements because whatever is the number of diet books purchased, the number of pounds lost by the average dieter does not change.
- The variable ‘number of diet books purchased’ shall appear on the horizontal axis and the variable ‘number of pounds lost by average dieter’ shall appear on the vertical axis.
- Even if the variable on the horizontal axis increases, the variable on the vertical axis will remain unchanged. Thus, there is no relationship between the two variables indicating that the slope is zero.
Conclusion:
Thus, the slope is zero.
(f) Regardless of its price, people buy the same quantity of salt.
- Panel (b) matches the given statements because whatever is the price of salt, the quantity of salt purchased remains the same.
- The variable ‘quantity of salt’ shall appear on the horizontal axis and the variable ‘price of salt’ shall appear on the vertical axis.
- Even if the variable on the vertical axis increases, the variable on the horizontal axis will remain unchanged. Thus, the slope shall be:
Conclusion:
Thus, the slope is infinity.

. What the heck is this GDP thingy?
It is Thursday afternoon, just a few days before the holiday season starts in your region, and you decided to visit your uncle Chao who owns a local delivery company. While sitting in the living room watching the evening news with your uncle, you heard the news reporter stating the following with an optimistic tone: "According to recent studies, gross domestic product (GDP) is rising due to an increase in consumer spending. The increase in spending was due to an increase in consumer confidence because the job market has shown a positive increase in both employment and income."
Immediately, your uncle Chao looked at you with some confusion on his face and asked:
What the heck is GDP, and why does the news dude seem excited about its increase?
Does this “good” change in this GDP thingy have any effect on my delivery business? How?
Do I need to do something different to prepare for the rise in GDP? How?

- 3. I need people who don’t want me! As an operations manager at a factory that produces manual tools, you were tasked with preparing a new site for expansion. The plan is to start production in the new location within 6 months from the current date. The new location requires 100 workers to operate fully. The workers you need don’t require any form of education or special skills because the tasks at the factory are simple and straightforward. In other words, you typically hire lower-skilled workers. In recent years, your company has been having problems finding workers who meet those criteria because the demand for them is so high. While sitting in your office, your teammate, Alejandra, walked to your office and said, "Have you heard the recent news about the economy? They said that investment has declined, and government spending has declined too. They also said that GDP is expected to shrink in the next 6 to 10 months. I wonder what is next."

For the downstream mill, the marginal profitability of producing boxes declines with volume. For example, the first unit of boxes increases earnings by $10, the second by $9, the third by $8, and so on, until the tenth unit increases profit by just $1. The cost the upstream mill incurs for producing enough paper (one "unit" of paper) to make one unit of boxes is $3.50. Assume the two mills operate as separate profit centers, and the paper mill sets the price of paper. It follows that the marginal profitability of boxes represents the highest price that the box division would be willing to pay the paper division for boxes.. Furthermore, assume that fixed costs are $0 for the paper mill. The following table summarizes the quantity, total revenue, and marginal costs from the perspective of the paper mill for selling paper to the box mill at various prices. In the following table, fill in the marginal revenue, total cost, and total…arrow_forward
- Planes frequently push back from the gate on time, but then wait 2 feet away from the gate until it is time to queue up for takeoff. This increases fuel consumption and increases the time that passengers must sit in a cramped plane awaiting takeoff. The following table shows the pay schedule for the flight crew. Pay Per diem Holding pay per hour Flight Attendant Captain First Officer $3 $3 $3 $20 $20 $20 Hourly wage (after push back) $38 $184 $50 Per diem pay indicates how much the flight crew earns once it checks into the airport. Holding pay indicates how much the flight crew earns after it loads the plane. Hourly wage indicates how much the flight crew earns after it pushes back from the gate and turns on the beacon. In this scenario, who does not have an incentive to push back from the gate as early as possible? Check all that apply.
