Suppose we have a company, Freddie's, that sells all of its goods on credit ONLY. For the year ended 12/31/19, we are given the following: Sales (will all be credit) Accounts Receivable (1/1/19) Allowance for doubtful accounts (1/1/19), credit Cash Collections from '19 Accounts written off as uncollected in 19 $1,200,000 $225,000 $15,000 $1,050,000 $10,000 a) What is the balance in the accounts receivable account at 12/31/19? b) If Freddie's estimates bad debts at 2% of credit sales, what will they record as bad debt expense for 2019? c) Based on your answer to b, what journal entry would Freddie's prepare to record bad debt expense for 2019? (You do not need to do this - only explain what they would do). d) If Freddie's estimates bad debts using the aging method and the aging schedule estimates $30, 100 of the year-end accounts receivable will be uncollected, what amount will they record as bad debt expense for '19? e) Based on your answer to d, what journal entry would Freddie's prepare to record bad debt expense for 2019?
