Follow-up Question
A corporation manufactures candles at two locations. The cost of producing x1 units at location 1 is
C1 = 0.02x12 + 4x1 + 900
and the cost of producing x2 units at location 2 is
C2 = 0.05x22 + 4x2 + 375.
The candles sell for $12 per unit. Find the quantity that should be produced at each location to maximize the profit
P =
12(x1 + x2) – C1 – C2.
X1 =
X2
