Answer:
B. $248,100
Explanation:
The difference between the receivables balance at the start of the year and at the end is as a result of credit sales to customers( increase receivables balance ) and cash collected from customers ( reduces the receivables balance).
Let the amount of sale on account be Y
$122,550 + Y - $200,000 = $170,650.
Y = $170,650 + $200,000 - $122,550
Y = $248,100
