The budget constraint of the consumer.
Explanation of Solution
The budget constraint is the constraint which is due to the budget of the individual. The human wants and needs are unlimited and when the budget of the individual is not unlimited, it will lead to the constraint of needs and this constraint raised due to the limited budget is known as the budget constraint of the individual. Thus, a budget constraint will represent all the possible combinations of two commodities that an individual can consume at the given market prices and with all his income in hand.
Here, the income of the person is given as $3,000, the price of per glass wine is $3 and the price of cheese is $6. Thus, when the consumer spends her entire income on the purchase of cheese, the quantity that she can receive can be calculated by dividing the income with per pound price as follows:
Thus, when she spends all her income on cheese, she can buy 500 pounds of cheese. When she spends all her income on the wine, the quantity can be calculated by replacing the price of cheese with that of wine as follows:
Thus, when she spends all her income on wine, she can receive 1,000 glasses of wine.
The budget constraint represents all the combinations of these two goods ranging between 500 pounds of cheese and no wine to no cheese and 1,000 glasses of wine. The vertical axis represents wine and the horizontal represents cheese on our diagram. The 500 pounds of cheese and no wine point represent the horizontal intercept and the no cheese and 1,000 glasses of wine represent the vertical intercept. The budget constraint can be drawn as follows:
The slope of the budget constraint is the rise over the run. It can be calculated by dividing the negative vertical intercept (represented by –b) by the horizontal intercept (represented by a) as follows:
Thus, the slope of the budget constraint is -2.
Concept introduction:
Budget constraint: It represents all the combinations of two goods that the consumer can consume with the given price level and the income in the hands of the individual.

- What is a budget constraint? A consumer has an income of $3000. Soda costs $3 per liter and cheese costs $6 per pound. Draw the consumer's budget constriaint with soda on the vertical axis. What is the slope of the budget constraint?arrow_forwardMarie has a weekly budget of $24, which she likes to spend on magazines and pies. Calculate: a) If the price of a magazine is $4 each, what is the maximum number of magazines she could buy in a week? b) If the price of a pie is $12, what is the maximum number of pies she could buy in a week? c) Draw Marie’s budget constraint with pies on the horizontal axis and magazines on the vertical axis. What is the slope of the budget constraint? d) What is Marie’s opportunity cost of purchasing a pie? NOTE: To answer this question simply work your answer in a piece of paper, take a photo of it and upload the file. Remember that this is a problem solving question, hence you must show your work!arrow_forwardJessie has a budget of $50 and is attempting to draw her budget constraint for purchasing cookies and strawberries. At a maximum, she could consume 100 strawberries; she labels this point on the vertical axis of her budget constraint. If the slope of her budget constraint is -4, what is the price of a cookie?arrow_forward
- If Joe decides to allocate his entire weekly allowance between energy drinks and coffee, he could afford 9 energy drinks and 3 cups of coffee, or 6 cups of coffee and 2 energy drinks. Suppose a cup of coffee costs £2.80. a) Calculate the price of an energy drink and Joe's weekly allowance. Write down Joe's budget equation and draw the corresponding budget line. Mark the two consumption bundles mentioned above. In your graph, clearly label the axes, the budget line, and calculate the coordinates of the points of intersection of the budget line with each axis. Interpret each of those points. b) Discuss how Joe's budget set would change if his allowance was reduced by £5.20 a week. Show the relevant changes graphically. How should the price of coffee change so that Joe could still afford to buy 6 cups of coffee and 2 energy drinks? c) Discuss how Joe's budget constraint would change if the government subsidised consumption of coffee by £0.50 per cup of coffee.arrow_forwardsuppose you have a fixed income of $3000 per month and you want to allocate your budget between two products: X and Y. Let's say the price of good x is $10 per unit, and the price of good y is $20 per unit. What is the budget constraint? Draw it on a graph and label the intercepts and the slope.arrow_forwardSuppose you have a budget of 30 to spend on two goods: pizzas and burgers. Each pizza is $5 while each burger is $10.

- Peter loves spicy food. He consumes both Laoganma chili crisp and Texas Pete hot sauce. His annual budget curve maps from (20 bottles of Laoganma, 0 cups of Texas Pete) to (0 bottles of Laoganma, 24 bottles of Texas Pete). a) Draw his budget constraint. Express the price of Texas Pete, in terms relative to the price of Laoganma. b) Given this set up, would Peter ever consume at the following points of (#bottles of Laoganma, #bottles of Texas Pete)? Why/why not? If we would consume at this point, draw an indifference curve that would justify this decision.i) (12, 12) ii) (6, 15) iii) (6, 6) iv) (12, 10) c) Imagine that Peter consumes 4 bottles of Laoganma. How many bottles of Texas Pete will he consume?d) Now imagine that the price of Texas Pete doubles. Draw the new budget constraint in Laoganma / Texas Pete space. e) Assume Peter goes from the consumption point found in part c of this question to a new point where he consumes 5 bottles of Laoganma to some new consumption point defined…arrow_forwardRaymond consumes meatloaves and pineapples.
