To calculate the total account balance after 35 years with a simple interest rate of 4% per year, we can use the formula:
Total balance = Principal + (Principal * Interest Rate * Time)
In this case, the principal (initial investment) is $33, the interest rate is 4% (or 0.04 as a decimal), and the time is 35 years. Plugging these values into the formula, we get:
Total balance = $33 + ($33 * 0.04 * 35)
Calculating the expression inside the parentheses:
Total balance = $33 + ($33 * 0.04 * 35)
= $33 + ($33 * 1.4)
= $33 + $46.2
= $79.2
Therefore, the total account balance after 35 years would be approximately $79.2.
