- Assume that you are on an island where there are only two commodities—coconuts and pineapples—and you can spend your income only on these two foods. If the price of coconuts is Pc and the price of pineapples is Pp and your income is I, draw a budget constraint, carefully labelling the points on the two axes and where the attainable and unattainable portions of consumption are. Note: you can choose any Pc and Pp that you like—they do not have to be equal. What is the slope of this budget constraint? What is the economic interpretation of the slope? Now, let’s bring a little more structure to this diagram. Let I=£200, Pc=£1 per coconut and Pp=£2 per pineapple. Draw a new diagram using these numbers. Consider these questions: How many coconuts can you buy if you do not buy any pineapples? How many pineapples can you buy if you do not buy any coconuts? What is the slope and what economic information does it give us? Show the point of 100 coconuts and 100 pineapples on your diagram.

The price of the lemon soda (PX) is $2 per bottle, and the price of the chips (PY) is $4 price Write down Lucas’s budget constraint. Draw the budget constraint on the graph below. Make sure to indicate the intercepts and the slope of budget constraint. Label it as BC1. Provide an economic interpretation of the slope of the budget constraint BC1 Suppose Lucas’s income decreases to $12 per week, and the price of lemon soda and chips remain the same. Write down Lucas’s new budget constraint. Then draw his new budget constraint on the same graph above. Make sure to indicate the intercepts and the slope. Label it as BC2. Suppose Lucas’s income remains to be $40 per week and the price of chips remains the same, but the price of lemon soda (PX) increases to $5. Write down Lucas’s new budget constraint. Then draw his new budget constraint on the same graph above. Make sure to indicate the intercepts and the…arrow_forwardO 0 (2 18 8. Normal and inferior goods Megan likes going to the ballpark to watch baseball, and she also is fond of going to the theater to listen to the symphony orchestra. The following diagram shows two of Megan's indifference curves for going to ballgames and symphonies. With Megan's initial budget constraint (BC), she chose to go to five symphonies and three baseball games per month (point X). Then her budget constraint shifted to BC, and she chose to go to four symphonies and six ballgames per month (point Y), SEOTING 2 4 SYMPHONIES BCarrow_forward
- pats >125 per week to spend on peanut butter and carrots in the fixed ratio of 1 pound of peanut butter to 4 pounds of carrots. Peanut butter costs $1 per pound and carrots cost $0.5 per pound Suppose the price of carrots were to rise from $05 to $1 per pound. By how much will Tom have to reduce his consumption of carrotsarrow_forwardQuestion 3: Samantha has $3,000 to spend on two goods: sandwiches and beer. The price of a sandwich is $6 and price of a beer is $5. a) Draw Samantha's budget line. Put beer on the horizontal axis. b) If Samantha's optimal consumption bundle contains 400 sandwiches, how many beer does her optimal consumption bundle contain? Show her optimal consumption in the graph above. c) Draw Samantha's indifference curve crossing her optimal consumption bundle.arrow_forwardAndrea has a budget of £21 to spend on toothbrushes and tooth paste. He does not receive any utility from owning a toothbrush, but for the consumption of every tube of tooth paste he gains a utility of 2 utils – but only if he owns a tooth brush. Without a tooth brush, Andrea gains no utility from consuming tooth paste. In addition, after consuming 10 tubes of tooth paste, a toothbrush needs to be replaced, i.e., Andrea needs to buy a new one. The current price of tooth brushes on the market is £5 and the current price for tooth paste is £1 per tube. Assume that Andrea aims to maximise consumer surplus. a) In a graph, draw total utility as a function of number of toothpaste tubes, assuming that Andrea buys 1 tooth brush. b) How many tubes will Andrea buy if he wants to maximise consumer surplus, assuming that Andrea can buy any amount of tooth brushes? What is Andrea's total consumer surplus? c) How many tubes will he buy if the current price is £0.50 per tube? e d) Find Andrea's…arrow_forward
- Suppose Sam has a weekly budget of $48 to spend on juice and yogurt. Juice is priced at $4 per gallon, and yogurt is priced at $2 per container. gallons of juice. If he spends his entire $48 on yogurt, he can buy containers of If Sam spends his entire $48 on juice, he can buy yogurt. Use the blue line (circle symbol) to plot Sam's budget constraint on the following graph. Next, use the orange point (square symbol) to shade the area that represents combinations of juice and yogurt that are affordable for Sam. Finally, place the black point (plus symbol) on the point on Sam's budget constraint that corresponds to a scenario in which Sam spends $24 on each good.

If he uses his income only for apples, he can buy 10 pounds. If he uses his income only for bananas, he can buy 15 pounds. Which one is the correct formula for his budget constraint when X=pounds of apples, Y=pounds of bananas and the prices are per pound? a) More information is needed to answer the question. b) 15X + 10Y = 300 c) 10X + 15Y = 300 d) 20X + 30Y = 300 e) 30X + 20Y = 300arrow_forward
