Assume that a Japanese car manufacturer exports cars to U. S. dealerships, which are priced in yen. The demand for those cars declines when the yen is strong. The manufacturer also produces some cars in the U. S. with U. S. materials and those cars are priced in dollars. The manufacturer could reduce its economic exposure by: a. pricing its exports in dollars. b. closing down most of its plants in the U. S. c. relying completely on Japanese suppliers for its parts. d. producing more automobiles in the U. S.

Until recently, hamburgers at the city sports arena cost $4.70 each. the food concessionaire sold an average of 13 comma 000 hamburgers on game night. when the price was raised to $5.40, hamburger sales dropped off to an average of 6 comma 000 per night. (a) assuming a linear demand curve, find the price of a hamburger that will maximize the nightly hamburger revenue. (b) if the concessionaire had fixed costs of $1 comma 500 per night and the variable cost is $0.60 per hamburger, find the price of a hamburger that will maximize the nightly hamburger profit.
