Question
Chase plans to buy a new car and determines he can budget $725 monthly for four years. His bank is offering an 8.25% annual interest rate. What is the maximum loan he can afford to stay in his budget?
Use the formula, A=P[(1+rn)nt−1]rn(1+rn)nt
, where P is the monthly payment, r is the annual interest rate, n is the number of times interest is compounded in one year, and t is the number of years.

To determine how much Chase can afford to borrow based on his monthly budget, we can use the formula for the future value of an ordinary annuity which essentially rearranges the compound interest formula. The A value represents the total amount Chase will pay in loan payments.
The formula given can be rearranged to find P, which is his maximum loan payment, with the parameters being:
- P = monthly payment (which is $725)
- r = annual interest rate (8.25% = 0.0825)
- n = number of times the interest is compounded annually (for this scenario, we can assume monthly compounding, so n = 12)
- t = number of years (4 in this case)
To calculate the maximum loan amount (\(A\)), we can use the formula below:
\[
A = P \cdot \frac{(1 + \frac{r}{n})^{nt} - 1}{\frac{r}{n}(1 + \frac{r}{n})^{nt}}
\]
1. Substitute the values into the formula:
- \(P = 725\)
- \(r = 0.0825\)
- \(n = 12\)
- \(t = 4\)
2. Plug these values into the formula step-by-step:
\[
A = 725 \cdot \frac{(1 + \frac{0.0825}{12})^{12 \times 4} - 1}{\frac{0.0825}{12}(1 + \frac{0.0825}{12})^{12 \times 4}}
\]
Calculating the fractions:
\[
\frac{r}{n} = \frac{0.0825}{12} \approx 0.006875
\]
\[
nt = 12 \cdot 4 = 48
\]
\[
(1 + 0.006875)^{48} \approx 1.43236465412
\]
Now, substituting back into the formula:
\[
(1.43236465412 - 1) \approx 0.43236465412
\]
Now substituting back into the formula:
\[
A = 725 \cdot \frac{0.43236465412}{0.006875 \cdot 1.43236465412}
\]
Calculating \(0.006875 \cdot 1.43236465412\):
\[
0.006875 \cdot 1.43236465412 \approx 0.009839421788
\]
So now we can compute \(A\):
\[
A = 725 \cdot \frac{0.43236465412}{0.009839421788} \approx 725 \cdot 43.9235214 \approx 31,842.25
\]
However, the question asks for the maximum loan, and I realize we have made an algebraic error in the loan payment structure.
Let's correct it based on a present value of annuity formula:
Using this method,
At an 8.25% annual interest rate, using:
Using the present value annuity formula:
\[
PV = PMT \cdot \left(1 - (1 + r)^{-nt}\right) / r
\]
PMT = 725
r = 0.0825 / 12 = 0.006875
nt = 4 * 12 = 48
Calculate the maximum principal amount (PV):
\[
PV = 725 \cdot \frac{1 - (1 + 0.006875)^{-48}}{0.006875}
\]
Calculating \((1 + 0.006875)^{-48}\):
\[
= (1 + 0.006875)^{-48} \approx 0.7516286
\]
Thus,
\[
PV = 725 \cdot \frac{1 - 0.7516286}{0.006875}
= 725 \cdot \frac{0.2483714}{0.006875}
\approx 72475.88
\]
