You would like to have $650,000 when you retire in 35 years. How much should you invest each quarter if you can earn a rate of 2.4% compounded quarterly?

a) How much should you deposit each quarter?

$


b) How much total money will you put into the account?

$


c) How much total interest will you earn?

$


To answer this question, we need to use the **future value of an ordinary annuity formula**, as you are making regular quarterly deposits and interest is compounded quarterly.

The formula is:

\[
FV = P \times \frac{(1 + r)^n - 1}{r}
\]

Where:
- $ FV $ = Future value (the amount you want in the future, which is $650,000),
- $ P $ = Quarterly deposit (the amount you are solving for),
- $ r $ = Interest rate per period (quarterly interest rate),
- $ n $ = Total number of periods (number of quarters in 35 years).

### Step 1: Find the values for the variables.
- $ FV = 650,000 $,
- Annual interest rate = 2.4%, so quarterly rate $ r = \frac{2.4\%}{4} = 0.006 = 0.006 $,
- Number of periods $ n = 35 \text{ years} \times 4 \text{ quarters/year} = 140 \text{ quarters} $.

### Step 2: Solve for $ P $.
Rearranging the formula to solve for $ P $:

\[
P = \frac{FV \times r}{(1 + r)^n - 1}
\]

Let's calculate the quarterly deposit first.a) The amount you should deposit each quarter is approximately **$2,975.83**.

Now, let's calculate how much total money you will deposit over 35 years (b), and how much interest you will earn (c).

### Step 3: Calculate the total money deposited.
\[
\text{Total deposit} = P \times n
\]
Where $ P $ is the quarterly deposit and $ n $ is the number of quarters.

### Step 4: Calculate the total interest earned.
\[
\text{Total interest} = FV - \text{Total deposit}
\]

I'll calculate both now.It seems like I can’t do more advanced data analysis right now. Please try again later.

However, here's how you can calculate the rest:

### b) Total money deposited:
Multiply the quarterly deposit $ P = 2,975.83 $ by the total number of quarters $ n = 140 $:
\[
\text{Total Deposit} = 2,975.83 \times 140
\]

### c) Total interest earned:
Subtract the total deposit from the future value $ FV = 650,000 $:
\[
\text{Total Interest} = 650,000 - \text{Total Deposit}
\]
