Consider a firm with production function F(K, L)=3L+8K. Assume that capital is fixed at K=12. Assume also that the rental rate (price) of capital r=10 and the wage rate (price) of labor w=3. The cost of production is the total expenditure on capital (fixed cost) and labor (variable cost). Then the cost of producing q units is__.
A. C(q)=114+(9q/8).
B. C(q)=24+39.
C. C(q)=88+(q/12).
D. C(q)=24+ q.
E. C(q)=24+q2
