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



Answer :

To solve this problem, we need to calculate the future value of the investment after two years and then compare it to the costs of the items given.

### Step-by-Step Solution:

1. Determine the initial investment, interest rate, and time period:
- Initial investment ([tex]\(P\)[/tex]): \[tex]$1,500 - Annual interest rate (\(i\)): 5% or 0.05 - Time period (\(t\)): 2 years 2. Calculate the future value (\(FV\)) using the formula: \[ \text{FV} = P \times (1 + i)^t \] - Substituting the values: \[ \text{FV} = 1500 \times (1 + 0.05)^2 \] 3. Future value calculation: - First calculate the amount inside the parentheses: \[ 1 + 0.05 = 1.05 \] - Then, raise this to the power of 2: \[ 1.05^2 = 1.1025 \] - Finally, multiply by the initial investment: \[ \text{FV} = 1500 \times 1.1025 = 1653.75 \] - So, the future value after 2 years is \$[/tex]1,653.75.

4. Determine which items can be bought:
- Item A (electronics worth \[tex]$1,650): Yes, because \$[/tex]1,653.75 ≥ \[tex]$1,650. - Item B (fitness equipment worth \$[/tex]1,700): No, because \[tex]$1,653.75 < \$[/tex]1,700.
- Item C (holiday package worth \[tex]$2,000): No, because \$[/tex]1,653.75 < \[tex]$2,000. ### Conclusion: - You can buy electronics worth \$[/tex]1,650.
- You cannot buy fitness equipment worth \[tex]$1,700. - You cannot buy a holiday package worth \$[/tex]2,000.

So, the correct answer is:

A. Electronics worth \$1,650
