Please help me find the total revenue, total expenses and income tax expenses. I'm subtracting my equipment rental fees and equipment rental fee earned but the answer is still wrong. Please show me step by step on how to solve this.

On December 1, Year 1, Wayne and Susan Li formed a corporation called French Broad Equipment Rentals.

The newly formed company uses the following accounts:

The corporation performs adjusting entries monthly. Closing entries are performed annually on December 31. During December of its first year of operations, the corporation entered into the following transactions:

December 1 Issued to Wayne and Susan Li 20,000 shares of capital stock in exchange for a total of $240,000 cash.

December 1 Purchased for $288,000 all of the equipment formerly owned by Rent-It. Paid $168,000 cash and issued a one-year note payable for $120,000. The note, plus all 12 months of accrued interest, are due November 30, Year 2.

December 1 Paid $14,400 to Shapiro Realty as three months advance rent on the rental yard and office formerly occupied by Rent-It.

December 4 Purchased office supplies on account from Modern Office Company, $1,200. Payment due in 30 days. (These supplies are expected to last for several months; debit the Office Supplies asset account.)

December 8 Received $9,600 cash as advance payment on equipment rental from McNamer Construction Company. (Credit Unearned Rental Fees.)

December 12 Paid salaries of $6,240 for the first two weeks in December.

December 15 Excluding the McNamer advance, equipment rental fees earned during the first 15 days of December amounted to $21,600, of which $14,400 was received in cash.

December 17 Purchased on account from Earth Movers, Incorporated, $720 in parts needed to perform basic maintenance on a rental tractor. Payment is due in 10 days.

December 23 Collected $2,400 of the accounts receivable recorded on December 15.

December 26 Rented a backhoe to Mission Landscaping at a price of $300 per day, to be paid when the backhoe is returned. Mission Landscaping expects to keep the backhoe for about two or three weeks.

December 26 Paid biweekly salaries, $6,240.

December 27 Paid the account payable to Earth Movers, Incorporated, $720.

December 28 Declared a dividend of 12 cents per share, payable on January 15, Year 2. (Hint: Credit the Dividends Payable account.)

December 29 French Broad Equipment Rentals was named, along with Mission Landscaping and Collier Construction, as a co-defendant in a $30,000 lawsuit filed on behalf of Kevin Davenport. Mission Landscaping had left the rented backhoe in a fenced construction site owned by Collier Construction. After working hours on December 26, Davenport had climbed the fence to play on parked construction equipment. While playing on the backhoe, he fell and broke his arm. The extent of the companys legal and financial responsibility for this accident, if any, cannot be determined at this time. (Note: This event does not require a journal entry at this time but may require disclosure in the notes accompanying the statements.)

December 29 Purchased a 12-month public liability insurance policy for $11,520. This policy protects the company against liability for injuries and property damage caused by its equipment. However, the policy goes into effect on January 1, Year 2, and affords no coverage for the injuries sustained by Kevin Davenport on December 26.

December 31 Received a bill from Universal Utilities for the month of December, $840. Payment is due in 30 days.

December 31 Equipment rental fees earned during the second half of December amounted to $24,000, of which $18,720 was received in cash.
