Answer to Question 1

The indifference curve will be L-shaped. This shape indicates that more of either product, without any more of the other, would not make the consumer better off.

Answer to Question 2

Average total cost is total cost divided by output. Marginal cost is the change in total cost divided by the change in output. Marginal cost equals average total cost when the average total cost is at its minimum.
