Beyond the Answer

To find out how much interest Alex will earn on his savings bond, you can use the formula for simple interest:
where is the principal amount ($1500), is the interest rate (6% or 0.06), and is the time in years. Assuming Alex keeps the bond for 1 year, the calculation would be:
.
So, Alex will earn $90 in interest after one year!
If Alex continues to hold the bond for subsequent years, that interest amount will increase linearly since simple interest doesn’t compound. For example, after 5 years, he would earn , giving him a total of $1950, including his initial investment. Isn’t it amazing how a little patience can grow your money?
