Final answer:
The balance in the accounts receivable account at year end is -$26,075. The balance in the allowance for doubtful accounts at year end is -$4,172.
Step-by-step explanation:
To determine the balance in the accounts receivable account at year end, we need to calculate the net credit sales. Net credit sales can be calculated by subtracting the write-offs of uncollectable accounts receivable from the sales for the year. So, net credit sales = Sales for the year - Write-offs of uncollectable accounts receivable = $525,000 - $32,700 = $492,300.
The balance in the accounts receivable account at year end can be calculated by subtracting the cash collected on accounts receivable for the year from the net credit sales. So, balance in the accounts receivable account at year end = Net credit sales - Cash collected on accounts receivable for the year = $492,300 - $518,375 = -$26,075.
The balance in the allowance for doubtful accounts at year end can be calculated by multiplying the overall rate used to estimate the allowance for doubtful accounts at year end with the balance in the accounts receivable account at year end. So, balance in the allowance for doubtful accounts at year end = Overall rate * Balance in accounts receivable account at year end = 16% * -$26,075 = -$4,172.
