- 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 shouldBrenda wants to buy new car and has a budget of $25,000. She has just found a magazine that assigns each car an index for styling and an index for gas mileage. Each index runs from 1 to 10, with 10 representing either the most styling or best gas mileage. While looking at the list of cars, Brenda observes that on average, as the style index increases by one unit, the price of the car increases by $6,250. She also observed that as the gas-mileage index rises by one unit, the price of the car increases by $5,000. Illustrate the various combinations of style (S) and gas mileage (G) that Brenda could select with her $25,000 budget. Using the line drawing tool, illustrate Brenda's budget line. Label this line 'Budget Line'. Carefully follow the instructions above, and only draw the required object. Suppose Brenda's preferences are such that she always receives two times as much satisfaction from an extra unit of styling as she does from gas mileage. What type of car will Brenda choose?…Jessica has an income of $216 and she is buying apple cider and books. Apple cider is $8 per unit and books are $24 each.

- Aria consumes only two goods, food and clothing. The marginal utility of the last dollar she spends on food is 12, and the marginal utility of the last dollar she spends on clothing is 9. The price of food is $1.20/unit, and the price of clothing is $0.90/unit. Is Aria maximizing her utility?8. Normal and inferior goods Antonio likes going to the ballpark to watch baseball, and he also is fond of going to the theater to listen to the symphony orchestra. The following diagram shows two of Antonio's indifference curves for going to ballgames and symphonies. With Antonio's initial budget constraint (BC1), he chose to go to four symphonies and six baseball games per month (point X). Then his budget constraint shifted to BC2, and he chose to go to five symphonies and three ballgames per month (point Y). BALLGAMES 3 8 10 0 4 5 SYMPHONIES BC 8 BC 10 ? Of the following choices, which could have shifted Antonio's budget constraint from BC₁ to BC2? Check all that apply.
