The Smith Company made and sold 10,000 picnic tables last year. When output was
between 5,000 and 10,000 tables, its average variable cost was $24. In this output range,
each table contributed 60 percent of its revenue to fixed costs and profits.
(a) What was the price per table?
(b) If the Smith Company increases its price by 10 percent, how many tables will it have to
sell next year to obtain the same profit as last year?
(c) If the Smith Company increases its price by 10 percent, and if its average variable cost
increases by 8 percent as a result of wage increases, how many tables will it have to sell
next year to obtain the same profit as last year?
