Julie buys food and other goods. She has an income of $400 per month. The price of food is initially $1.00 per unit. It then rises to $1.20 per unit. The prices of other goods do not change. To help Julie out, her mother offers to send her a check each month to supplement her income. Julie tells her mother, “Thanks, Mom. If you would send me a check for $50 per month, I would be exactly as happy paying $1.20 per unit as I would have been paying $1.00 per unit and not receiving the $50 from you.” Which of the following statements is true? Explain. The increased price of food has: a) an income effect of +$50 per month b) an income effect of -$50 per month c) a compensating variation of +$50 per month d) a compensating variation of -$50 per month e) an equivalent variation of +$50 per month f ) an equivalent variation of -$50 per month

Wendy drinks 10 sugary drinks and 4 smoothies a week. Smoothies are $5 each and sugary drinks were $2 each. This week, things are different: the government has slapped a tax on sugary drinks and their price has doubled to $4. But it's not all bad news for Wendy. The government has also revised the income tax, so Wendy's drinks budget has increased. She can now just afford to buy her usual 10 sugary drinks and 4 smoothies a week.

A consumer has a budget set aside for entertainment during the year, and they spend the budget on concerts and plays. The consumer has a strong preference for attending concerts over plays: the two activities are substitutes, but not very strong substitutes. Sketch the indifference curves for this consumer on a graph, with concert tickets on the vertical axis and play tickets on the horizontal axis. Briefly explain why the consumer might ultimately choose to purchase a large number of play tickets, even though they have a strong preference for concerts. Include a budget line on your graph to illustrate this case.

True or false.  A budget constraint, budget line or budget set is a graphical way to illustrate all possible combinations of two goods that a person can afford.

34) Consider Dianna who has a $25 fast food budget per month. She can purchase salads (S), hamburgers (H), or chicken strips (C). The price of a salad is Ps=$3, the price of a hamburger is PB-$2 and the price of chicken strips is Pc $4. Fill in the table below. You will use your solutions to answer questions 34-36. # Hamburgers # Salads 1 2 2 MU Salads 36 30 c) 4; 3; 4 d) 5; 4; 5 MU/P Salads 1 2 3 4 5 MU hamburgers 5 In the optimal consumption bundle for Dianna, she will purchase chicken strips. a) 2; 1; 2 b) 3; 2; 3 28 22 16 36) Dianna total utility from her consumption bundle is a) 126 b) 504 c) 106 d) 398 MU/P # Hamburgers Chicken Strips T 2 3 7 salads, 4 5 35) Dianna's utility is maximized where the marginal utility per dollar spent on each item is equal to a) $10 b) $12 c) $14 d) $16 MU Chicken Strips 72 64 56 48 40 hamburgers, and MU/P Chicken Strips

The prices she's considering are shown in the table below. Calculate the utility for each of the prices in the table. What is the average of the calculated utilities?

Suppose the marginal utility of a Coke is 15 utils, and its price is $1.50. The marginal utility of a pizza is 20 utils, and its price is $5. To achieve consumer equilibrium, you need to spend
