Heather wants to save money to purchase a car. She buys an annuity with yearly payments that earn [tex]2\%[/tex] interest, compounded annually. Payments will be made at the end of each year. Find the total value of the annuity in 3 years if each yearly payment is [tex]\$ 5996[/tex].

Do not round any intermediate computations, and round your final answer to the nearest cent.

Answer :

To find the total value of the annuity after 3 years with annual payments of [tex]$5996, an interest rate of 2% compounded annually, we can use the future value of an annuity formula: \[ A = M \left[ \frac{(1 + \frac{r}{n})^{nt} - 1}{\frac{r}{n}} \right] \] Where: - \(A\) is the future value of the annuity, - \(M\) is the yearly payment, - \(r\) is the annual interest rate, - \(n\) is the number of times the interest is compounded per year, - \(t\) is the number of years. Given: - \(M = 5996\), - \(r = 0.02\), - \(n = 1\) (compounded annually), - \(t = 3\), We can plug these values into the formula to calculate the future value of the annuity. ### Step-by-Step Solution 1. First, substitute the given values into the formula: \[ A = 5996 \left[ \frac{(1 + \frac{0.02}{1})^{1 \cdot 3} - 1}{\frac{0.02}{1}} \right] \] 2. Compute the inside of the parenthesis: \[ 1 + \frac{0.02}{1} = 1 + 0.02 = 1.02 \] 3. Raise this value to the power of \(nt\): \[ (1.02)^{1 \cdot 3} = (1.02)^3 = 1.061208 \] 4. Subtract 1 from this value: \[ 1.061208 - 1 = 0.061208 \] 5. Divide by \(\frac{0.02}{1}\): \[ \frac{0.061208}{0.02} = 3.0604 \] 6. Multiply this result by the yearly payment \(M\): \[ 5996 \times 3.0604 = 18350.1568 \] 7. Round the final answer to the nearest cent: \[ 18350.16 \] So, the total value of the annuity in 3 years is \( \$[/tex] 18350.16 \).
