As at December 31 , three-quarters of these goods had been delivered. 2. There is \( \$ 2,020 \) in wages awed at year end. 3. Rent is paid in advance on the las day of each month. There was a balance of \( \$ 3,040 \) The trial balance for Cullumber Fireplaces Inc. far December 31, 2024, follaws: 1. The deposits from customers were far future deliveries. As at December 31 , three-quarters of these goods had been delivered. 2. There is \( \$ 2,020 \) in wages awed at year end. 3. Rent is paid in advance on the las day of each month. There was a balance of \( \$ 3,040 \) in the Prepaid Rent account on January 1 , 2024. At the end of January, \$3,040 was paid for the February rent and was debited to the Prepaid Rent account. All the rent payments during the year were treated the same way. The rent for July to December increased to \( \$ 4,040 \) per month (Hint Determine the amount of rent expense for 2024 , as well as the correct amount that has been prepaid for 2025 , and make an adjustment that will bring bath these accounts to the carrect balances.) 4. A count of the supplies at year end revealed that \( \$ 510 \) of supplies were still on hand. 5. The building is being depreciated over 20 years with a residual value of \( \$ 20,200 \). 6. The bank loan was taken cut on Appril 1, 2024. The first interest payment is due an April 1, 2025. The interest rate is 10\%. 7. Income tax for the year should be calculated using a tax rate of \( 30 \% \). (Hint After you finish the other ad/usting entries, you will have to determine the income before income tax and then calculate the tax as \( 30 \% \) of this amaunt.] Prepare the adjusting entries for the year 2024.
