Select the correct answer.

If you invest [tex]$\$1,500$[/tex] today in a bank that gives you a 5 percent annual interest rate, which of these items can you buy in two years?

[tex]
\begin{array}{l}
\text{future value} = P \times (1 + i)^t \\
\text{present value} = \frac{P}{(1 + i)^t}
\end{array}
[/tex]

A. electronics worth [tex]$\[tex]$1,650$[/tex][/tex]
B. fitness equipment worth [tex]$\$1,700$[/tex]
C. a holiday package worth [tex]$\[tex]$2,000$[/tex][/tex]



Answer :

To determine which items you can buy in two years if you invest \[tex]$1,500 at an annual interest rate of 5%, we need to calculate the future value of this investment using the compound interest formula: \[ \text{Future Value} = P \times (1 + i)^t \] Where: - \( P \) is the initial principal (the amount of money you start with), - \( i \) is the annual interest rate, - \( t \) is the number of years the money is invested. Given: - \( P = 1500 \) dollars, - \( i = 0.05 \) (5 percent as a decimal), - \( t = 2 \) years. Plugging in the values: \[ \text{Future Value} = 1500 \times (1 + 0.05)^2 \] \[ \text{Future Value} = 1500 \times 1.05^2 \] \[ \text{Future Value} = 1500 \times 1.1025 \] \[ \text{Future Value} = 1653.75 \] So, after 2 years, the investment will be worth \$[/tex]1653.75.

Next, we will compare this future value with the prices of the items:

- Electronics: \[tex]$1650 - Fitness equipment: \$[/tex]1700
- Holiday package: \[tex]$2000 Now we check which items can be purchased with \$[/tex]1653.75:

- The price of the electronics (\[tex]$1650) is less than or equal to \$[/tex]1653.75, so you can buy the electronics.
- The price of the fitness equipment (\[tex]$1700) is greater than \$[/tex]1653.75, so you cannot buy the fitness equipment.
- The price of the holiday package (\[tex]$2000) is greater than \$[/tex]1653.75, so you cannot buy the holiday package.

Therefore, the correct answer is:

A. Electronics worth \$1650
