Final answer:
The marginal cost is the change in total cost resulting from producing one additional unit of output. To draw the marginal cost curve, plot the quantity of generators on the x-axis and the corresponding marginal cost on the y-axis.
Step-by-step explanation:
Marginal cost is the change in total cost resulting from producing one additional unit of output. To find the marginal cost for each generator, you would calculate the change in total cost between producing one generator and producing one more generator. For example, if producing one generator costs $100 and producing two generators costs $200, the marginal cost for the second generator would be $200 - $100 = $100.
To draw the marginal cost curve, you would plot the quantity of generators on the x-axis and the corresponding marginal cost on the y-axis. The curve would typically slope upward since as more generators are produced, the cost of producing an additional unit increases. The shape of the marginal cost curve will depend on various factors such as economies of scale, production technology, and input costs.
