Suppose you want to have \( \$ 600,000 \) for retirement in 35 years. Your account earns \( 10 \% \) interest. How much would you need to deposit in the account each month?

The formula for simple interest is \( I=P r t \), where \( P= \) principal, \( r= \) rate, and \( t= \) time. Solve the formula for \( r \). \( \begin{array}{l} r=\frac{t I}{P} \\ r=\frac{P t}{l} \\ r=\frac{P I}{t} \\ r=\frac{l}{P t}\end{array} \)

posited \( \$ 3400 \) into a savings account \( 0.2 \% \). Find the amount in the savings

You deposit \( \$ 1000 \) each year into an account earning \( 3 \% \) interest compounded annually. How much will you have in the account in 25 years? \( \$ \)
