Tutors-Plus Test Prep was organized on May 1, 2013, by Jan Cooper. Jan is a good manager but a poor accountant. From the trial balance prepared by a part-time bookkeeper, Jan prepared the following income statement for her fourth quarter, which ended April 30, 2014.

TUTORS-PLUS TEST PREP Income Statement For the Quarter Ended April 30, 2014 Revenues Service revenue $240,000 Operating expenses Advertising expense $ 6,400 Salaries and wages expense 92,000 Utilities expense 1,300 Depreciation expense 2,400 Maintenance and repairs expense 1,700 Total operating expenses 103,800 Net income $136,200 Jan suspected that something was wrong with the statement because net income had never exceeded $40,000 in any one quarter.

1 Service revenue includes advance payments received for summer classes, in the amount of $75,000.
2 There were $2,600 of supplies on hand at April 30.
3 Prepaid insurance resulted from the payment of a one-year policy on February 1, 2014.
