UpStudy AI · Accepted Answer

We are given that you want a future value of  
$$
\$5000
$$  
in $$5$$ years by making deposits at the end of every six months into an annuity with a nominal interest rate of $$6\%$$ compounded semiannually. This means the interest rate per six‐month period is  
$$
i = \frac{6\%}{2} = 3\% = 0.03.
$$
Since deposits are made every six months for $$5$$ years, the total number of payments is  
$$
n = 5 \times 2 = 10.
$$

### Part (a): Find the Deposit Amount

For an ordinary annuity (deposits at the end of each period), the future value is given by the formula  
$$
FV = R \frac{(1+i)^n - 1}{i},
$$
where $$R$$ is the deposit made at the end of each period. We set $$FV = 5000$$ and solve for $$R$$:

$$
5000 = R \frac{(1.03)^{10} - 1}{0.03}.
$$

First, compute $$(1.03)^{10}$$. Using a calculator (or logarithms) we get approximately

$$
(1.03)^{10} \approx 1.343916379.
$$

So,

$$
(1.03)^{10} - 1 \approx 1.343916379 - 1 = 0.343916379.
$$

Now, solve for $$R$$:

$$
R = \frac{5000 \times 0.03}{0.343916379} \approx \frac{150}{0.343916379} \approx 436.91.
$$

The instruction is to round up to the nearest dollar, so

$$
R \approx \$437.
$$

### Part (b): Compute the Contribution from Deposits and Interest

**Total Deposits:**  
Since you make $$10$$ deposits and each deposit (after rounding) is $$\$437$$,

$$
\text{Total Deposits} = 10 \times 437 = \$4370.
$$

**Interest Earned:**  
The interest portion is the difference between the future value and the total deposits:

$$
\text{Interest} = 5000 - 4370 = \$630.
$$

Thus, the breakdown of the $$\$5000$$ is:

- $$\$4370$$ comes from your deposits.
- $$\$630$$ comes from the interest earned.

$$
\boxed{
\begin{array}{l}
\text{(a) Deposit Amount: } \$437 \text{ every six months,} \
\text{(b) Composition: } \$4370 \text{ from deposits and } \$630 \text{ from interest.}
\end{array}
}
$$
To have \$5000 in 5 years with 6% interest compounded semiannually, you should deposit \$437 at the end of every six months. This results in \$4370 from deposits and \$630 from interest.
