Jerry spends his entire budget on bread and gasoline. His preferences are complete, transitive, monotonic, and convex. For Jerry, bread is an inferior good that follows the law of demand. Moreover, his cross-price elasticity of demand for gasoline with respect to the price of bread is negative. Suppose the price of bread increases, all else constant. a. Create a chart to show the total, income, and substitution effects on bread and gasoline of the increase in the price of bread. b. Use budget lines and indifference curves to graphically illustrate the three effects. Be sure to label each effect on your graph (or through the chart from part a) and plot bread on the x-axis and gasoline on the y-axis

8. Sara’s income is $12 a week. The price of popcorn is $3 a bag and the price of cola is $1.50 a can. The figure below shows Sara’s indifference curves for popcorn and cola. In the picture popcorn is on y-axis and cola on x-axis. a. What quantity of popcorn and cola does Sara buy to maximize her well being? What is Sara’s marginal rate of substitution at the point at which she consumes? b. Suppose that the price of cola rises from $1.50 to $3.00 a can while the price of popcorn and Sara’s income remain the same. What quantities of cola and popcorn does Sara now buy? c. What are two points on Sara’s demand curve for cola? Draw Sara’s demand curve.
Question 3 Maureen spends her budget on pizza and salad. Suppose that the price of salad increases, as a result, she decreases her consumption on salad. (1) Discuss the substitution effect due to the price increase. Will Maureen consume more or less salads due to the substitution effect? (2) Discuss the income effect due to the price increase. Will Maureen consume more or less salads due to the income effect? Discuss briefly, with max. 5-6 lines for each effect. You can also draw a graph if it helps you.
Heart spends her entire weekly food allowance of $42 on fries and milk tea. The price of a fries is $2, and the price of milk tea is $1. Heart purchases 12 fries and 18 milk tea, and her marginal rate of substitution between fries and milk tea is 1. Is Heart in equilibrium? Explain
Peter consumes only chocolate ice cream and vanilla ice cream. He is spending all of his income. His marginal utility of chocolate is 200 and his marginal utility of vanilla is 200, and the price of chocolate is $1.00 per scoop and the price of vanilla is $2.00 per scoop. To maximize his utility, Peter should
Cho lives in Miami and loves to eat desserts. She spends her entire weekly allowance on pudding and pie. A bowl of pudding is priced at $1.50, and a piece of pumpkin pie is priced at $4.50. At her current consumption point, Cho's marginal rate of substitution (MRS) of pudding for pie is 5. This means that Cho is willing to trade five bowls of pudding per week for one piece of pie per week.

Carlos is originally consuming his optimal consumption bundle of cell phones and gasoline when the price of gasoline falls. Assume that both gasoline and cell phones are normal goods. How will a decrease in the price of gasoline affect your consumption of cell phones and gasoline? Explain using the substitution and income effects.
