each machine are as follows:

The shaper is available for 120 hours, and the grinder for 110 hours. No more than 250 units of component 3 can be sold, but up to 1,000 units of component 1 and up to 1,000 units of
component 2 can be sold. In fact, the company already has orders for 550 units of component 1 that must be satisfied. The per unit selling price and per unit variable costs for each of the three
components are as follows:

Component Selling price Material Cost Labor Cost

(a) For each component, calculate the profit margin (profit margin
Component 1: $
600
Component 2: $
700
Component 3: $
200
=
selling price - material cost - labor cost).
Formulate and solve the model to determine the maximum profit. If the constant is "1", it must be entered in the box. If an amount is zero, enter "0".
Let C1
= units of component 1 manufactured
C2 = units of component 2 manufactured
C3 = units of component 3 manufactured
