ANSWER
You will earn $1903593 in the first investment than the second investment
EXPLANATION;
Given that;
For the first investment;
Prinicipal = $23, 000
time = 40 years
interest rate = 12%
For the second investment
Principal = $23, 000
time = 40 years
interest rate = 6%
Follow the steps below to find the amount of each investment after 40 years
Note that; the investment was compounded annually
Hence, n = 1
Write the compound interest formula
![\text{ A = P \lparen 1 + }\frac{\text{ r}}{\text{ n}})^{n*\text{ t}}](https://img.qammunity.org/2023/formulas/mathematics/college/xgvu9afgyk2npfpiim8mdx5rs3o0uaubz9.png)
For the first investment
![\begin{gathered} \text{ A = 23000 \lparen 1 + }(0.12)/(1))^(1*40) \\ \text{ A = 23000 \lparen1 + 0.12\rparen}^(40) \\ \text{ A = 23000\lparen1.12\rparen}^(40) \\ \text{ A = 23000 }*\text{ 93.050} \\ \text{ A = \$2140150} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ezau1m4uhsgefy9kpo58qt5ni7vlor4fax.png)
For the second investment
![\begin{gathered} \text{ A = P \lparen 1 + }\frac{\text{ r}}{\text{ n}})^(n* t) \\ \text{ A = 23000 \lparen 1 + }(0.06)/(1))^(1*40) \\ \text{ A = 23000 \lparen1 + 0.06\rparen}^(40) \\ \text{ A = 23000 \lparen1.06\rparen}^(40) \\ \text{ A = 23000}*10.285 \\ \text{ A = \$ 236555} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/z7uq87yh2mm2rtvs9uiv4uybo5pct3ekh7.png)
Subtract the total amount realized in investmment 2 from investment 1
So, we have
![\text{ \$2140150 - \$236555 = \$1903595}](https://img.qammunity.org/2023/formulas/mathematics/college/573raahklximu0zv0m5txh08p9v6q4rgxh.png)
Therefore, you will earn $1903593 in the first investment than the second investment
