Correct Answer: Option B
Explanation

To get Q, we first have to solve for P, hence we have;

Total cost (P) = fixed cost + variable

750 + 900 = 1650

Marginal cost (Q) = 1650 - 1310 = 340

Quantity (kg) Fixed cost ($) Variable cost ($) Total cost ($) Marginal cost ($) Average cost ($)
1 750 200 950 - 950
2 750 560 1310 360 655
3 750 900 1650 340 550
