To solve this problem, we will follow the same steps as before but with the updated values:

1. Calculate the down payment: $25\%$ of the sailboat's cost.
2. Calculate the loan amount: Subtract the down payment from the total cost.
3. Calculate the monthly payment: Using the amortizing loan formula.
4. Calculate the total interest paid.

Let's compute these values step-by-step.

1. Down Payment

The sailboat costs $\$21,835$ and the down payment is $25\%$.

$\text{Down Payment} = 0.25 \times 21835$

2. Principal Loan Amount

$\text{Principal} = \text{Total Cost} - \text{Down Payment}$

3. Monthly Payment

The annual interest rate is $7.2\%$ compounded monthly, so the monthly interest rate $r$ is: $r = \frac{7.2\%}{12} = 0.006$ The loan term is 8 years, so the number of payments $n$ is: $n = 8 \times 12 = 96$

Now, let's calculate these values.### Results

1. Down Payment: $5,458.75
2. Principal Loan Amount: $16,376.25
3. Monthly Payment: $224.90 (rounded to two decimal places)
4. Total Amount Paid: $21,590.65
5. Total Interest Paid: $5,214.40
