Answer: the answer is given below
Explanation:
It should be noted that the account receivable ending balance was calculated as:
Credit sales = 156,000
Less: collection of account= 132,300
Less: written off = 6,300
= 17,400
The bad debt expense was calculated as:
= (17,400 × 10%) + 6300
= (17400 × 0.1) + 6300
= 1740 + 6300
= 8040
