Answer: $140
Explanation:
Based on the information given in the question, the marginal cost of producing the 50th acre of sod will be:
TC = 0.2Q² + 120Q + 5000
The marginal cost will be:
= dTC / dQ
= 0.4Q + 120
Then we put the value of Q = 50 into the equation and this will be:
MC = 0.4Q + 120
MC = (0.4 x 50) + 120
MC = 20 + 120
MC = 140
