Let's analyze and solve the questions in the image.
### Question 1: For each of the following variables, indicate whether it is quantitative or categorical. Then, identify the individual (or case) and write a sentence explaining why you might be interested in such a variable.
#### a. The number of calories in a cup of breakfast cereal
- **Type**: Quantitative
- **Individual**: A cup of breakfast cereal
- **Interest**: This variable is important for nutritional analysis and diet planning, helping individuals manage their calorie intake.
#### b. Salaries of last year's college graduates
- **Type**: Quantitative
- **Individual**: Last year's college graduates
- **Interest**: Understanding salary ranges can provide insights into job market trends and help new graduates set salary expectations.
#### c. Preferred brand of cola
- **Type**: Categorical
- **Individual**: Consumers
- **Interest**: Companies can use this information for market research to identify popular brands and tailor their marketing strategies.
#### d. Time it takes college freshmen to read a particular editorial
- **Type**: Quantitative
- **Individual**: College freshmen
- **Interest**: This data can be used to study reading comprehension and speed, which can help in developing educational programs.
#### e. Race of small business owners in Philadelphia
- **Type**: Categorical
- **Individual**: Small business owners in Philadelphia
- **Interest**: This information is useful for demographic studies and can help in creating policies to support diversity in business ownership.
### Question 2: A store advertises its discounts in two parts. Here is the offer: "Take 50% off of the original price, then take another 30% off of that." Suppose a shirt you want to buy originally cost $25.00.
#### a. If there is a single discount of 50%, how much would the shirt cost?
- **Calculation**: \( 25.00 \times 0.50 = 12.50 \)
- **Answer**: $12.50
#### b. If we now apply the second discount of 30% to the discounted price of the shirt from part (a), what is the cost?
- **Calculation**: \( 12.50 \times 0.70 = 8.75 \)
- **Answer**: $8.75
#### c. With the "double discount" as described, what is the total percentage discount deducted from the original price?
- **Calculation**: First discount: 50%, second discount on the reduced price: \( 50\% + (0.50 \times 30\%) = 50\% + 15\% = 65\% \)
- **Answer**: 65%
#### d. Would that "double discount" percentage be the same for an item with a different original price? Explain your answer.
- **Explanation**: Yes, the percentage discount would remain the same because the discounts are applied multiplicatively. The sequence of applying 50% followed by 30% on the new price remains consistent regardless of the original price.
#### e. Why do you think the store uses this two-part advertising method?

Masks (Now).
The easing Covid-19 pandemic is expected to reduce demand for medical masks this year, joining a group of companies that have forecast a decline in business from Covid-19 prevention.
Masks became a billion-dollar business for the St. Paul, Minn., manufacturer starting in 2020, when the virus’s rapid spread sent consumers and healthcare workers looking to secure facial coverings to try to avoid infection. Now, as the latest U.S. surge caused by the Omicron variant fades, 3M said they are seeing slowing mask sales.

You participate in a taste test for a new protein supplement called "Kapow." You are given five consecutive one ounce vials of the supplement and after consuming each vial you are asked to note your reaction. You consume the first vial and your response is: "Hmmm, quite good!" After the second, you say, "Not bad at all." After the third, you note, "It's alright." and after the fourth you wince, "No more, the after-taste is getting to me. I need water." What economic principle does this scenario illustrate? Define the principle.

1. In her last-minute preparations for final exams, a student has set aside five hours to
split between studying for two subjects, finance and economics. Her goal is to
maximize the average grade received in the two courses. (Note that maximizing the
average grade and maximizing the sum of the grades are equivalent goals.)
According to her best guesses, grades vary with study as follows:

b. How much time should the student spend studying each subject?
c. Suppose the student also is taking an accounting exam and estimates that each
hour of studying will raise her grade by three points. She has allotted two hours
for studying accounting (in addition to the five hours
already mentioned). Is this an optimal decision? Explain. (Assume her objective
is to maximize her average grade across the three courses.)

"DIFFERENCE BETWEEN NEEDS AND WANTS"
It is very important to find the difference between
want & need. The money that would be spent on
things that you may want in that moment could
instead be saved or put into things that are more
important. By doing this you may see that you can
save a lot of money, by not buying things that are
not needed and even and that most of your money
is not even being spent

For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the
previous graph has a slope that reflects this type of relationship.
X-axis
Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and
vertical axis. For example, in the first scenario, X-axis should be labeled The average grade received" and Y-axis should be labeled "The number of
hours spent studying".
Scenario
As the number of hours spent studying rises, the average grade received rises.
As the number of hours spent studying falis, the likelihood of getting an A falls.
As the number of hours spent watching TV rises, the average grade received falls.
True
True or False: Line B has a slope of infinity.
