Answer:
$697
Explanation:
Marginal cost is the additional cost incurred as a result of increasing the number of items produced. Marginal cost is used to optimize production.
The marginal cost is gotten by differentiating the cost function, it is given by:
Marginal cost = C'(x)
The cost is given as C(x)=52x²+85x+560.
Given that the marginal cost should be less than $270, hence:
C'(x) < 270
104x + 85 < 270
104x < 270 - 85
104x < 185
x < 185/104
x < 1.77
Therefore x ≈ 1
C(1) = 52(1²) + 85(1) + 560 =
C(1) = $697
