Answer:
Cash was collected from customers during the year was $ 104,100
Explanation:
Sales revenue = $120,000
Bad debt expense = 2.5% of sales
Therefore, Bad debt expense = $120,000 x 2.5% = $3,000
Thus, allowance for uncollectible accounts should have increased by $3,000. But it increased by $2,100.
Therefore, uncollectible accounts receivable of $900 ($3,000 - $2,100) were written off during that year.
Cash collected from customers = Sales revenue - Increase in accounts receivable - Uncollectible accounts written off
= $120,000 - $15,000 - $900
= $104,100
