When a company has a policy of making sales for which credit is extended, it is reasonable to expect a portion of those sales to be uncollectible. As a result of this, a company must recognize bad debt expense. There are basically two methods of recognizing bad debt expense: (1) direct write-off method, and (2) allowance method.

Instructions

(b) Discuss the reasons why one of the above methods is preferable to the other and the reasons why the other method is not usually in accordance with generally accepted accounting principles.

Debit Credit
Accounts receivable \$80,000
Allowance for doubtful accounts 730
Sales \$340,000
Sales returns and allowances 8,000

Give journal entries assuming that the estimate of uncollectibles is determined by taking (1) 5% of gross accounts receivable and (2) 1% of net sales.

8.-Present value of an investment in equipment. (Tables needed.)
Find the present value of an investment in equipment if it is expected to provide annual savings of \$10,000 for 10 years and to have a resale value of \$25,000 at the end of that period. Assume an interest rate of 9% and that savings are realized at year end.

9-Future value of an annuity due. (Tables needed.)
If \$4,000 is deposited annually starting on January 1, 2010 and it earns 9%, how much will accumulate by December 31, 2019?

How much must be invested now to receive \$20,000 for ten years if the first \$20,000 is received today and the rate is 8%?

11.-Compute the annual rent. (Tables needed.)
Crone Co. has machinery that cost \$80,000. It is to be leased for 15 years with rent received at the beginning of each year. Crone wants a return of 10%. Compute the amount of the annual rent.
