Suppose you won $15 on a lotto ticket at the local 7-Eleven and decided to spend all the winnings on candy bars and bags of peanuts. Candy bars cost $0.75 each while bags of peanuts cost $1.50 each. a. Construct a table showing the alternative combinations of the two products that are available. b. Plot the data in your table as a budget line in a graph. What is the slope of the budget line? What is the opportunity cost of one more candy bar? Of one more bag of peanuts? Do these opportunity costs rise, fall, or remain constant as additional units are purchased? c. Does the budget line tell you which of the available combinations of candy bars and bags of peanuts to buy? d. Suppose that you had won $30 on your ticket, not $15. Show the $30 budget line in your diagram. Has the number of available combinations increased or decreased?

Marie has a weekly budget of $24, which she likes to spend on magazines and pies.
If the price of a magazine is $4 each, what is the maximum number of magazines she could buy in a week?
If the price of a pie is $12, what is the maximum number of pies she could buy in a week?

At the start of the week, Marie decides to buy a pie. Does this imply that the utility she receives from this pie is greater than or less than her opportunity cost of purchasing the pie?
Marie is thinking about purchasing a second pie. Do we expect the marginal utility she receives from the second pie to be greater than, less than, or equal to the marginal utility she receives from the first pie? Explain your answer.

- . Your best friend has just purchased a new Sport Utility Vehicle (SUV). “These things are great.” he says. “They can get you to the private unspoiled places no one else can reach. On the road, it’s nice because you sit so high and can see over the other cars.” Your friend thinks everyone should buy an SUV. Is there an error in his reasoning? If so, what is it? (Use economics terms).arrow_forwardKatie loves swimming. Every afternoon, she visits the local swimming pool for a swim. The entry cost to the pool costs Katie $10 but she can swim for as long as she wants. Once she has entered the pool and paid the fee, Katie wonders how many hours should she spend swimming if she were to think like an economist. She expects to gain an incremental benefit of $21 from the first hour of swimming, then gains subsequent incremental benefits of $17 from the second, $11 from the third and $4 from the fourth. For every hour spent swimming, it will cost Katie $6 as she could have spent the time doing her homework. In determining how many hours Katie should be swimming, the $10 entry fee to the pool is a/an Type A for Average cost, M for Marginal cost, S for Sunk cost or O for Opportunity cost. Using marginal analysis, what is the optimal amount of hours Katie should spend swimming? The maximum surplus for Katie, from spending the number of hours you found in part b, is $ Answer to the nearest…arrow_forwardConsider the following two situations. (i) You purchase a $10 movie ticket in advance over the Internet, but when arriving at the theater, you realize that you lost the ticket. The only way to see the movie is to purchase a new ticket.(ii) On the way to seeing a movie, you drop a $10 bill. You still can afford the movie, but you have lost the $10. How should you, a rational person, respond to the two situations? You should still see the movie in both situations. You should respond the same way to each situation, whether it is to see the movie or not. In each situation, you should not see the movie. In the first situation, you should skip the movie; in the second, you should still see the movie.arrow_forward
