Answer:
The answer shown in the question,$91300 is correct
Step-by-step explanation:
In computing the operating expenses,the proforma below applies:
Cash payment for operating expenses =$97000
add prepayment for last year =$17500
less prepayment this year =($23200)
Operating expenses $91700
The prepaid expenses last year were added because they were paid in advance last year for expenses incurred this year while prepaid expenses this year were deducted since they are prepaid this year for expenses to be incurred next year.
This above is valid because expenses are to recognized when incurred not when paid for.
