Andy consumes two goods, books and video games. His income is $40, the price of a video game is $8, and the price of a book is $4. Suppose Andy's parents give him $24 for his birthday. 1.) Using the triangle drawing tool, show Andy's budget set on the top graph to the right. Label your triangle 'BS1'. https://imgur.com/undefined Carefully follow the instructions above and only draw the required object. Now suppose Andy's parents had given him three video games for his birthday instead of giving him $24. Andy is a very polite young man and would never return a gift that his parents had given him for cash or to him parents. 1.) Using the multipoint curve drawing tool, show the budget constraint that Andy now faces on the graph to the right. Label your curve 'BS2'. (Hint: The budget constraint is simply a subset of the budget set; graphically, it is the outer edge of the budget set that separates affordable bundles from unaffordable bundles.) https://imgur.com/qtZu1Yv Carefully follow the instructions above and only draw the required object. Based on your preceding answers, which of the following is possible? (Check all that apply.) A. He could be indifferent between a gift of $24 and a gift of three video games. B. Andy could prefer a gift of $24 to a gift of three video games. C. He could prefer a gift of three video games to a gift of $24.

How does a consumer's budget set differ from his budget constraint? A. A budget set refers to all of the possible bundles of goods and services a consumer can purchase, while a budget constraint is limited to the bundles he can purchase using all of his income. B. A budget constraint refers to all of the possible bundles of goods and services a consumer can purchase, while a budget set is limited to the bundles he can purchase using all of his income. C. A budget set is simply the collection of the many budget constraints a consumer faces at different points in time. D. There is no difference at all—the terms "set" and "constraint" are interchangeable. For a consumer with a given level of income, the combinations of goods for the budget set will be __________ than for the budget constraint.
A. A budget set refers to all of the possible bundles of goods and services a consumer can purchase, while a budget constraint is limited to the bundles he can purchase using all of his income. Higher
Charley spends all of his income on soft drinks and pizza. Suppose he is currently buying these products in amounts such that his marginal benefit from an additional soft drink is $160 and his marginal benefit from an additional slice of pizza is $70. If the price of a soft drink is $4 and the price of a slice of pizza is $5, is Charley maximizing his total benefits? A. No, he should shift consumption toward soft drinks and away from pizza to maximize total benefits. B. No, he should increase his consumption of both goods. C. No, he should shift consumption toward pizza and away from soft drinks to maximize total benefits. D. Yes, there is no other consumption choice that will make his total benefits greater.
A. No, he should shift consumption toward soft drinks and away from pizza to maximize total benefits.
John earns $4,800 per month. He spends all of his money on two goods, A and B. The price of good A is $240, and the price of good B is $400. Identify the intercepts of John's budget constraint if good A is plotted on the x-axis and good B is plotted on the y-axis. A. 8 units of good A on the x-axis and 20 units of good B on the y-axis B. 20 units of good A on the x-axis and 12 units of good B on the y-axis C. 10 units of good A on the x-axis and 8 units of good B on the y-axis D. 18 units of good A on the x-axis and 45 units of good B on the y-axis The slope of John's budget constraint is negative __________. (Round your response to two decimal places. Use a negative sign if you are entering a negative number.) Ria has an income of $1,200. She consumes two types of goods, shoes and handbags. Suppose the price of a pair of shoes is $400, and the price of a handbag is $200. What is the opportunity cost of each good? A.

These market-created benefits are referred to as ___________, and using the graph to the right, are represented by area ___. https://imgur.com/dBENxWt Suppose now that the market price rises. According to the graph, the excess of total benefits over the total amount spent by consumers will ___________.
Consumer surplus B Decrease
A gift shop sells ceramic figurines for $80 and crystal vases for $100. At these prices, the gift shop sells 12 ceramic figurines and 8 crystal vases per day. If the price of ceramic figurines falls to $64 and the price of crystal vases falls to $25, the quantity demanded of ceramin figurines and crystal vases will increase to 18 units and 12 units per day, respectively. If the gift shop wants to increase revenue, which of the following actions should be taken? A. Increase the price of both ceramin figurines and crystal vases. B. Decrease the price of ceramic figurines and increase the price of crystal vases. Your answer is correct. C. Increase the price of ceramic figurines and decrease the price of crystal vases. D. Decrease the price of both ceramic figurines and crystal vases. For a normal good, the income elasticity of demand ___________.

Given this information, John's total benefit from the plan will be ______. Suppose John plays video games for 4 hours. For the last hour, he decides to watch a movie over talking on the phone. His total benefit will __________ because the marginal benefit from watching a movie for 1 hour is __________ the marginal benefit from talking on the phone for 1 hour. John's total benefit will be maximum if he plays video games for ___ hour(s), talks on the phone for ___ hour(s), and watches a movie for ___ hour(s).
