$18,482, which was added to the Office Supplies account. The inventory of supplies available at December 31 totaled $3,938. b. The Prepaid Insurance account had a $30,624 debit balance at December 31 before adjusting for the costs of any expired coverage for the year. An analysis of prepaid insurance shows that $22,041 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.
