Understanding the Problem

Eva is looking to take out a 20-year mortgage from a bank offering a monthly interest rate of $0.325\%$ . The goal is to determine the maximum amount Eva can borrow, given that the highest monthly payment she can afford is $X$ . To solve this problem, we will use the formula for calculating the present value of an annuity, which is given by:

P = \frac{A}{r} \left( 1 - (1 + r)^{-n} \right)

where:

$P$ is the present value (the maximum amount Eva can borrow)
$A$ is the monthly payment (the highest monthly payment Eva can afford)
$r$ is the monthly interest rate (0.325% or 0.00325 as a decimal)
$n$ is the number of payments (20 years * 12 months/year = 240 months)

Step 1: Convert the Monthly Interest Rate to a Decimal

The monthly interest rate is given as $0.325\%$ . To convert this to a decimal, we divide by 100:

r = \frac{0.325}{100} = 0.00325

Step 2: Calculate the Number of Payments

The number of payments is given by the number of years multiplied by the number of months per year:

n = 20 \times 12 = 240

Step 3: Plug in the Values and Solve for P

Now that we have all the values, we can plug them into the formula and solve for $P$ :

P = \frac{A}{r} \left( 1 - (1 + r)^{-n} \right)

P = \frac{A}{0.00325} \left( 1 - (1 + 0.00325)^{-240} \right)

To find the maximum amount Eva can borrow, we need to find the value of $A$ that makes the equation true. However, since we are given that the highest monthly payment Eva can afford is $X$ , we can set $A = X$ and solve for $P$ .

Step 4: Calculate the Maximum Amount Eva Can Borrow

To calculate the maximum amount Eva can borrow, we need to find the value of $A$ that makes the equation true. Since we are given that the highest monthly payment Eva can afford is $X$ , we can set $A = X$ and solve for $P$ .

Let's assume that the highest monthly payment Eva can afford is $X = 1000$ . We can plug this value into the equation and solve for $P$ :

P = \frac{1000}{0.00325} \left( 1 - (1 + 0.00325)^{-240} \right)

P \approx 307,692.31

Since we are asked to round the answer to the nearest dollar, we can round $P$ to $307,692$ .

Conclusion

In this problem, we used the formula for calculating the present value of an annuity to determine the maximum amount Eva can borrow. We assumed that the highest monthly payment Eva can afford is $X = 1000$ and solved for $P$ . The result is that the maximum amount Eva can borrow is approximately $307,692$ .

Calculating the Maximum Amount Eva Can Borrow with Different Monthly Payments

In the previous section, we assumed that the highest monthly payment Eva can afford is $X = 1000$ . However, this value may not be realistic for Eva's financial situation. To determine the maximum amount Eva can borrow with different monthly payments, we can plug in different values of $A$ into the equation and solve for $P$ .

Step 1: Calculate the Maximum Amount Eva Can Borrow with a Monthly Payment of $500

Let's assume that the highest monthly payment Eva can afford is $A = 500$ . We can plug this value into the equation and solve for $P$ :

P = \frac{500}{0.00325} \left( 1 - (1 + 0.00325)^{-240} \right)

P \approx 153,846.15

Since we are asked to round the answer to the nearest dollar, we can round $P$ to $153,846$ .

Step 2: Calculate the Maximum Amount Eva Can Borrow with a Monthly Payment of $750

Let's assume that the highest monthly payment Eva can afford is $A = 750$ . We can plug this value into the equation and solve for $P$ :

P = \frac{750}{0.00325} \left( 1 - (1 + 0.00325)^{-240} \right)

P \approx 230,769.23

Since we are asked to round the answer to the nearest dollar, we can round $P$ to $230,769$ .

Step 3: Calculate the Maximum Amount Eva Can Borrow with a Monthly Payment of $1000

Let's assume that the highest monthly payment Eva can afford is $A = 1000$ . We can plug this value into the equation and solve for $P$ :

P = \frac{1000}{0.00325} \left( 1 - (1 + 0.00325)^{-240} \right)

P \approx 307,692.31

Since we are asked to round the answer to the nearest dollar, we can round $P$ to $307,692$ .
