How much would you need to deposit in an account now in order to have $4,000.00 in the account in 18 years if the interest is:

(a) 9.54% simple interest?

To find out how much you need to deposit now to have $4,000 in 18 years with simple interest at a rate of 9.54%, you can use the simple interest formula:

\[
A = P(1 + rt)
\]

Where:
- $ A $ is the amount of money you will have in the future ($4,000),
- $ P $ is the principal (the amount you need to deposit now),
- $ r $ is the interest rate per year (9.54% or 0.0954),
- $ t $ is the time in years (18 years).

Rearranging the formula to solve for $ P $:

\[
P = \frac{A}{1 + rt}
\]

Now, let's plug in the values:

\[
P = \frac{4000}{1 + (0.0954 \times 18)}
\]

Calculating that:

\[
P = \frac{4000}{1 + 1.7172}
\]
\[
P = \frac{4000}{2.7172}
\]
\[
P \approx 1472.11
\]

So, you would need to deposit approximately **$1,472.11** now to have $4,000 in the account in 18 years with 9.54% simple interest.
