Can someone help me solve this linear programming problem?
A calculator company produces a scientific calculator and a graphing calculator. There is an expected demand of at least 60 scientific and 80 graphing calculators each day. Because of limitations on production capacity, no more than 100 scientific and 170 graphing calculators can be made daily. To satisfy a shipping contract, a total of at least 200 calculators must be shipped each day. If each scientific calculator is sold for a $2 profit and each graphing calculator is sold for a $5 profit, how many of each should be made daily to maximize profit? What is this maximum profit?
