Henderson Office Supply is considering a more liberal credit policy to increase sales, but expects that 8 percent of the new accounts will be uncollectible. Collection costs are 3 percent of new sales, production and selling costs are 80 percent, and the accounts receivable turnover is five times. Assume income taxes of 35 percent and an increase in sales of $82,000. No other asset buildup will be required to service the new accounts.

a. What additional investment in accounts receivable is needed to support this sales expansion?

b. What would be Henderson’s incremental aftertax return on investment? (Input your answer as a percent rounded to 2 decimal places.)

Assume that Henderson also needs to increase its level of inventory to support new sales and that the inventory turnover is two times.  

c. What would be the total incremental investment in accounts receivable and inventory needed to support a $82,000 increase in sales?
