Hello, I have spent hours but stuck on the last two sections of this problem and would appreciate any guidance. I've highlighted in Green the corrected entries.

Critical Thinking

Saira Morrow operates Dressage Riding Academy, Inc. The academys primary sources of revenue are riding fees and lesson fees, which are provided on a cash basis. Saira also boards horses for owners, who are billed monthly for boarding fees. In a few cases, boarders pay in advance of expected use. For its revenue transactions, the academy maintains these accounts: Cash, Accounts Receivable, Unearned Service Revenue, and Service Revenue. The academy owns 10 horses, a stable, a riding corral, riding equipment, and office equipment. These assets are accounted for in the following accounts: Horses, Buildings, and Equipment. The academy employs stable helpers and an office employee, who receive weekly salaries. At the end of each month, the mail usually brings bills for advertising, utilities, and veterinary service. Other expenses include feed for the horses and insurance. For its expenses, the academy maintains the following accounts: Supplies, Prepaid Insurance, Accounts Payable, Salaries and Wages Expense, Advertising Expense, Utilities Expense, Maintenance and Repairs Expense, Supplies Expense, and Insurance Expense. Sairas sole source of personal income is dividends from the academy. Thus, the corporation declares and pays periodic dividends. To account for stockholders equity in the business and dividends, two accounts are maintained: Common Stock and Dividends. During the first month of operations, an inexperienced bookkeeper was employed. Saira 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.

Question) What was the correct net income for May, assuming the bookkeeper originally reported net income of $5,400 after posting all 50 entries?
