Answer 1

Answer:

(c) $5

Explanation:

Remember, To calculate marginal cost, we divide the change in production costs by the change in quantity.

In this example, the change in production cost is $200 (for hiring an additional worker) while the change in quantity of taco is 40 (increase in marginal productivity).

The marginal cost= $200/40

we get $5 as the marginal cost.
