A calculator company produces a scientific calculator and a graphing calculator. Because of limitations on production capacity, no more than 220 scientific and 180 graphing calculators can be made daily. To satisfy a shipping contract, a total of at least 200 calculators much be shipped each day. If each scientific calculator sold results in a $2 profit, and each graphing calculator produces a $5 profit, how many of each type should be made daily to maximize net profits?
