Provide an appropriate response.To fill an order for 100 units of a product, a firm wishes to distribute the production between its two plants, Plant 1 and Plant 2. The total cost function is given byc = f(q1, q2) = 0.5
+ 2q1 + 32q2 + 500, where q1 and q2 are the number of units produced at Plants 1 and 2, respectively. How should the output be distributed in order to minimize costs?
What will be an ideal response?
q1 = 30, q2 = 70
