The future value of the ordinary annuity is \$76,046.25.

Solution

To find the future value of an ordinary annuity, we can use the formula: \[ FV = PMT \times \frac{(1 + r/n)^{nt} - 1}{r/n} \] Where: - \( FV \) = future value of the annuity - \( PMT \) = payment amount per period - \( r \) = annual interest rate (as a decimal) - \( n \) = number of compounding periods per year - \( t \) = number of years Given: - \( PMT = 2250 \) - \( r = 1.40\% = 0.014 \) - \( n = 4 \) (since it is compounded quarterly) - \( t = 8 \) Now, we can substitute these values into the formula step by step. 1. Calculate \( r/n \): \[ r/n = \frac{0.014}{4} \] 2. Calculate \( nt \): \[ nt = 4 \times 8 \] 3. Calculate \( (1 + r/n)^{nt} \): \[ (1 + r/n)^{nt} = \left(1 + \frac{0.014}{4}\right)^{32} \] 4. Finally, substitute everything back into the future value formula. Let's perform these calculations step by step. Calculate the value by following steps: - step0: Calculate: \(4\times 8\) - step1: Multiply the numbers: \(32\) Calculate or simplify the expression \( (1 + 0.014/4)^(4*8) \). Calculate the value by following steps: - step0: Calculate: \(\left(1+\frac{0.014}{4}\right)^{4\times 8}\) - step1: Divide the terms: \(\left(1+\frac{7}{2000}\right)^{4\times 8}\) - step2: Add the numbers: \(\left(\frac{2007}{2000}\right)^{4\times 8}\) - step3: Multiply the numbers: \(\left(\frac{2007}{2000}\right)^{32}\) - step4: Use the properties of exponents: \(\frac{2007^{32}}{2000^{32}}\) Calculate or simplify the expression \( 0.014/4 \). Calculate the value by following steps: - step0: Calculate: \(\frac{0.014}{4}\) - step1: Convert the expressions: \(\frac{\frac{7}{500}}{4}\) - step2: Multiply by the reciprocal: \(\frac{7}{500}\times \frac{1}{4}\) - step3: Multiply the fractions: \(\frac{7}{500\times 4}\) - step4: Multiply: \(\frac{7}{2000}\) Calculate or simplify the expression \( 2250 * ((1 + 0.0035)^(32) - 1) / 0.0035 \). Calculate the value by following steps: - step0: Calculate: \(\frac{2250\left(\left(1+0.0035\right)^{32}-1\right)}{0.0035}\) - step1: Add the numbers: \(\frac{2250\left(1.0035^{32}-1\right)}{0.0035}\) - step2: Convert the expressions: \(\frac{2250\left(\left(\frac{2007}{2000}\right)^{32}-1\right)}{0.0035}\) - step3: Subtract the numbers: \(\frac{2250\times \frac{2007^{32}-2000^{32}}{2000^{32}}}{0.0035}\) - step4: Multiply the numbers: \(\frac{\frac{9\times 2007^{32}-9\times 2000^{32}}{250^{31}\times 8^{32}}}{0.0035}\) - step5: Convert the expressions: \(\frac{\frac{9\times 2007^{32}-9\times 2000^{32}}{250^{31}\times 8^{32}}}{\frac{7}{2000}}\) - step6: Multiply by the reciprocal: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{250^{31}\times 8^{32}}\times \frac{2000}{7}\) - step7: Rewrite the expression: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{250^{31}\times 8^{32}}\times \frac{250\times 8}{7}\) - step8: Reduce the numbers: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{250^{30}\times 8^{32}}\times \frac{8}{7}\) - step9: Rewrite the expression: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{2^{30}\times 125^{30}\times 8^{32}}\times \frac{8}{7}\) - step10: Rewrite the expression: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{2^{30}\times 125^{30}\times 8^{32}}\times \frac{2^{3}}{7}\) - step11: Reduce the numbers: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{2^{27}\times 125^{30}\times 8^{32}}\times \frac{1}{7}\) - step12: Multiply the fractions: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{2^{123}\times 125^{30}\times 7}\) - step13: Multiply: \(\frac{9\times 2007^{32}-9\times 2000^{32}}{7\times 2^{123}\times 125^{30}}\) Now that we have completed the calculations, let's summarize the results: 1. The value of \( r/n \) is approximately \( 0.0035 \). 2. The value of \( nt \) is \( 32 \). 3. The value of \( (1 + r/n)^{nt} \) is approximately \( 1.118294 \). Now, we can substitute these values into the future value formula: \[ FV = 2250 \times \frac{(1.118294 - 1)}{0.0035} \] Calculating this gives us: \[ FV \approx 2250 \times \frac{0.118294}{0.0035} \approx 2250 \times 33.57085714 \approx 76046.248094 \] Finally, rounding to the nearest cent, the future value of the ordinary annuity is: \[ FV \approx \$ 76,046.25 \] Thus, the future value of the ordinary annuity is \( \$ 76,046.25 \).

To find the future value of an ordinary annuity, we can use the formula: \[ FV = PMT \times \frac{(1 + r/n)^{nt} - 1}{(r/n)} \] Where: - \( PMT = 2,250 \) - \( r = 0.014 \) (1.40% as a decimal) - \( n = 4 \) (quarterly compounding) - \( t = 8 \) Plugging in the values: 1. **Calculate \( r/n \)**: \[ \frac{r}{n} = \frac{0.014}{4} = 0.0035 \] 2. **Calculate \( nt \)**: \[ nt = 4 \times 8 = 32 \] 3. **Calculate \( (1 + r/n)^{nt} \)**: \[ (1 + 0.0035)^{32} \approx (1.0035)^{32} \approx 1.121752 \] 4. **Calculate the future value**: \[ FV = 2250 \left( \frac{1.121752 - 1}{0.0035} \right) \] \[ FV = 2250 \left( \frac{0.121752}{0.0035} \right) \] \[ FV = 2250 \times 34.07 \approx 76658.25 \] Therefore, the future value of the ordinary annuity is approximately \( \$ 76,658.25 \).
