The fuel economy (in miles per gallon) of a certain car is E(x) = −0.01x2 + 0.52x +10.4,
 where x is the driving speed (in miles per hour, 20 ≤ x ≤ 60).
 At what speed is fuel economy greatest?
x =  mph

Country Motorbikes Incorporated finds that it costs $300 to produce each motorbike, and that fixed costs are $1600 per day. The price function is p(x) = 700 − 5x,
 where p is the price (in dollars) at which exactly x motorbikes will be sold. Find the quantity Country Motorbikes should produce and the price it should charge to maximize profit. Also find the maximum profit.
