I saw two different answers for this on here. Can you do this one and make clear what is correct. Typed or in a chart please! Thank you!

At December 31, 2018 Washington Company had a credit balance of $2000 in its allowance for uncollectible account (allowance for bad debts). Washington using an aging of accounts receivable determined that the allowance in the allowance account at the end of 2018 should be $7000. A. What entry should Washington make to adjust the balance in allowance account at year end 2018? B. If, instead, Washington used the percentage of sales approach what would the bad debt expense entry be if total credit sales for the year 2018 amounted to $500,0,000 and the rate of loss on credit sales have historically been 1 percent?
