You are given the following cost function:

Cost equals 0.2 q cubed minus 6 q squared plus 80 q plus 150 Cost = 0.2q 3 ? 6 q 2 + 80 q +150.

Marginal cost is:

0.6 q squared minus 12 q plus 80 0.6q 2 ? 12 q + 80

The value of the average cost when output = 10 units is_____$

The value of the marginal cost when output = 10 units is_____$

The output level where average variable cost equals marginal cost is_____$
