Oscar consumes both video games and Pepsi.
a. Given the table, what is Oscar’s total utility from purchasing three video games and 2 Pepsis?
b. Assume that Oscar has a weekly income of $20. If the price of a video game is $5 and the price of Pepsi is $2, what quantity of video games and Pepsi maximizes Oscar’s utility (he does not use his money for any other purchases)?
c. Assume that the price of Coca Cola drops. Does this increase, decrease, or not change Oscar’s demand for Pepsi?
d. Suppose that Oscar’s income elasticity for Pepsi is -0.5. Does the value of Oscar’s income elasticity indicate that Pepsi is a normal good, an inferior good, a substitute, or a complement?
e. Suppose that when the price of video games increases by 20 percent, Oscar buys 10 percent fewer video games and 2 percent less of other computer equipment. Calculate the cross-price elasticity for video games and computer equipment and indicate if it is positive or negative.
