Selina Brennan · Answer 1

To determine the number of bats that should be produced for the minimum cost, differentiate the given equation and equate to zero.

dC (b) / dt = (0.06) (2) b - 7.2

0 = 0.12b - 7.2

The value of b from the derived equation is 60. Therefore, the company should produced 60 bats for the minimum cost. Thus, the answer is letter B.
