To construct an amortization table for Lenny's loan, we need to calculate the annual payment amount, interest portion, principal portion, and remaining balance for each year of the loan.

Step 1: Calculate the Annual Payment

Given:

• Loan amount ($P$): $7,000
• Annual interest rate ($r$): 12% or 0.12
• Number of years ($n$): 6 years
• Payment frequency: once per year

The formula for the annual payment ($A$) on an amortized loan is:

$A = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1}$

Plugging in the values:

$A = 7000 \times \frac{0.12(1 + 0.12)^6}{(1 + 0.12)^6 - 1}$

Let's calculate the annual payment.The annual payment Lenny needs to make is approximately $1,702.58.

Step 2: Construct the Amortization Table

For each year, we need to calculate:

1. Interest for the year: $\text{Interest} = \text{Remaining Balance} \times \text{Annual Interest Rate}$
2. Principal paid: $\text{Principal} = \text{Annual Payment} - \text{Interest}$
3. New remaining balance: $\text{Remaining Balance} = \text{Previous Balance} - \text{Principal}$

Let's construct the full amortization table for all six years.It seems like I can’t do more advanced data analysis right now. Please try again later. However, I can guide you through the steps to construct the amortization table manually if you'd like!

Here’s a brief outline of how you can proceed:

1. Year 1:

   • Interest: $7,000 \times 0.12 = 840$
   • Principal: $1,702.58 - 840 = 862.58$
   • New Balance: $7,000 - 862.58 = 6,137.42$

2. Year 2:

   • Interest: $6,137.42 \times 0.12 = 736.49$
   • Principal: $1,702.58 - 736.49 = 966.09$
   • New Balance: $6,137.42 - 966.09 = 5,171.33$

Continue this process for each year, updating the balance after each payment until the loan is fully repaid in the sixth year.
