Final answer:
The monthly payment for Alpha company's truck purchase would be $2,511.60, and the total amount of interest paid would be $1,196.
Step-by-step explanation:
To compute the monthly payment for Alpha company's purchase of the truck, we need to consider the initial loan amount after the down payment and the sales tax. The truck costs $24,000 plus an 8% sales tax, which equals to $24,000 + ($24,000 × 0.08) = $25,920. After the $2,000 down payment, the remaining balance is $25,920 - $2,000 = $23,920.
This remaining balance is to be paid with a 5% note over 10 monthly payments. Assuming the interest rate is simple interest applied to the balance (since the question doesn't specify compounding), the total interest paid would be $23,920 × 0.05 = $1,196. The total amount to be repaid is then $23,920 + $1,196 = $25,116.
Divide the total amount to be repaid by the number of payments to find the monthly payment amount: $25,116 ÷ 10 = $2,511.60.
Now, to calculate the total amount of interest paid on the purchase of the truck, we have already determined it to be $1,196.
