Ramona's employer pays her $50 per day regardless of her productivity

level and provides her with all the cola she can drink. Cola costs the

employer $2 per can.

(a) Copy the table above and add information on the fixed, variable,

and total cost.

(b) Graph and carefully label the total cost curve. (What is measured

on the horizontal and on the vertical axis?)

(c) Calculate and add the marginal cost per page of output at each

level of soda consumption.
