Johnson Electronics is considering extending trade credit to some customers previously considered poor risks. Sales would increase by $240,000 if credit is extended to these new customers. Of the new accounts receivable generated, 6% will prove to be uncollectible. Additional collection costs will be 72% of sales, and production and selling costs will be 25% of sales. The firm is in the 25% tax bracket.

a.) Compute the incremental income after taxes

b.) What will Johnson's incremental return on sales be if these new credit customers are accepted?

C.) If the receivable turnover ration is 4 to 1, and no other asset buildup is needed to serve the new customers, what will Johnson's incremental return on new average investment be?
