To find the current value of the rental contract, we need to calculate the future value of each quarterly payment and then sum them up.
First, let's calculate the future value of each quarterly payment using the compound interest formula:
A = P(1 + \frac{r}{n})^{nt}
Where:
A = future value
P = principal (quarterly payment)
r = annual interest rate (8% = 0.08)
n = number of compounding periods per year (quarterly = 4)
t = time in years
Let's substitute the given values into the formula:
A = 4500(1 + \frac{0.08}{4})^{4 \times 5}
Simplifying the exponent:
A = 4500(1 + 0.02)^{20}
Calculating the value inside the parentheses:
A = 4500(1.02)^{20}
Using a calculator or computer, we can find that:
(1.02)^{20} \approx 1.485947
Substituting this value back into the formula:
A \approx 4500 \times 1.485947
Calculating the result:
A \approx 6,686.26
Therefore, the current value of the rental contract is approximately $6,686.26.
