For its revenue transactions, the academy maintains the following accounts: No. 1 Cash, No. 5 Boarding Accounts Receivable, No. 27 Unearned Boarding Revenue, No. 51 Riding Revenue, No. 52 Lesson Revenue, and No. 53 Boarding Revenue. The academy owns 10 horses, a stable, a riding corral, riding equipment, and office equipment. These assets are accounted for in accounts No. 11 Horses, No. 12 Building, No. 13 Riding Corral, No. 14 Riding Equipment, and No. 15 Office Equipment. For its expenses, the academy maintains the following accounts: No. 6 Hay and Feed Supplies, No. 7 Prepaid Insurance, No. 21 Accounts Payable, No. 60 Salaries Expense, No. 61 Advertising Expense; No. 62 Utilities Expense, No. 63 Veterinary Expense, No. 64 May and Feed Expense, and No. 65 Insurance Expense.

During the first month of operations an inexperienced bookkeeper was employed. Lisa Ortega asks you to review the following eight entries of the 50 entries made during the month. In each case, the explanation for the entry is correct. Identify each journal entry that is correct. For each journal entry that is incorrect, prepare the entry that should have been made by the bookkeeper. Which of the incorrect entries would prevent the trial balance front balancing? What was the correct net income for May, assuming the bookkeeper reported net income of $4,500 after posting all 50 entries? What was the correct cash balance at May 31, assuming the bookkeeper reported a balance of $12,475 after posting all 50 entries (and the only errors occurred in the items listed above)
