Check my work a. The Office Supplies account started the year with a $2,625 balance. During the year, the company purchased supplies for $10,841, which was added to the Office Supplies account. The inventory of supplies available at December 31 totaled $2,310. b. The Prepaid Insurance account had a $31,320 debit balance at December 31 before adjusting for the costs of any expired coverage for the year. An analysis of prepaid insurance shows that $22,535 of unexpired insurance coverage remains at year-end. c. The company has 15 employees, who earn a total of $1,850 in salaries each working day. They are paid each Monday for their work in the five-day workweek ending on the previous Friday. Assume that December 31 is a Tuesday, and all 15 employees worked the first two days of that week. Because New Year's Day is a paid holiday, they will be paid salaries for five full days on Monday, January 6 of next year. d. The company purchased a building at the beginning of this year. It cost $610,000 and is expected to have a $45,000 salvage value at the end of its predicted 40-year life. Annual depreciation is $14,125. e. Since the company is not large enough to occupy the entire building it owns, it rented space to a tenant at $2,700 per month, starting on November 1. The rent was paid on time on November 1, and the amount received was credited to Rent Revenue. However, the tenant has not paid the December rent. The company has worked out an agreement with the tenant, who has promised to pay both December and January rent in full on January 31.
