Ryan starts an IRA (Individual Retirement Account) at the age of 24 to save for retirement. He deposits $300 each month. Upon retirement at the age of 65, his retirement savings is $560,979.68. Determine the amount of money Ryan deposited over the length of the investment and how much he made in interest upon retirement.

To solve this problem, we need to determine two things:

1. The total amount of money Ryan deposited into the IRA over the length of the investment.
2. The total interest earned upon retirement.

### Step 1: Determine the Total Amount Deposited

Ryan deposits \$300 every month from the age of 24 until he reaches 65. The period between 24 and 65 years is:

\[
65 - 24 = 41 \text{ years}
\]

Since he deposits monthly, the total number of deposits is:

\[
\text{Total Deposits} = 41 \times 12 = 492 \text{ months}
\]

The total amount deposited over the length of the investment is:

\[
\text{Total Amount Deposited} = 300 \times 492
\]

Let's calculate that.

\[
\text{Total Amount Deposited} = 300 \times 492 = 147,600
\]

### Step 2: Determine the Total Interest Earned

The total savings at retirement is \$560,979.68. To find the interest earned, we subtract the total amount deposited from the total savings:

\[
\text{Total Interest Earned} = \text{Total Savings} - \text{Total Amount Deposited}
\]

Substitute the values:

\[
\text{Total Interest Earned} = 560,979.68 - 147,600
\]

Calculating this gives:

\[
\text{Total Interest Earned} = 413,379.68
\]

### Summary

- **Total Amount Deposited:** \$147,600
- **Total Interest Earned:** \$413,379.68

Ryan deposited a total of **\$147,600** over the length of the investment, and he earned **\$413,379.68** in interest upon retirement.
