Answer:
(a) service revenue = $117,920
(b) operating expenses = $98,110
Explanation:
The computations are shown below:
a. For service revenue
= Cash receipts from customers + ending balance account receivable - beginning balance of accounts receivable
= $117,140 + $15,400 - $14,620
= $117,920
b. For operating expenses
= Cash payments for operating expenses + beginning balance of prepaid expense - ending balance of prepaid expense
= $104,320 + $20,400 - $26,610
= $98,110
