! Required information (The following information applies to the questions displayed below.] At the beginning of 2021, Brad's Heating & Air (BHA) has a balance of $25,800 in accounts receivable. Because BHA is a privately owned company, the company has used only the direct write-off method to account for uncollectible accounts. However, at the end of 2021, BHA wishes to obtain a loan at the local bank, which requires the preparation of proper financial statements. This means that BHA now will need to use the allowance method. The following transactions occur during 2021 and 2022. 1. During 2021, install air conditioning systems on account, $188,000. 2. During 2021, collect $183,000 from customers on account. 3. At the end of 2021, estimate that uncollectible accounts total 10% of ending accounts receivable. 4. In 2022, customers' accounts totaling $7,800 are written off as uncollectible. 3. Calculate bad debt expense for 2021 and 2022 under the allowance method and under the direct write-off method, prior to any adjusting entries in 2022. (Leave no cells blank.)
