Question

Find the simply interest earned on an investment of $15,000 at a rate of 5.25% for two years.

Answer 1

Ok so you know that simple interest formula is
Simple interest= money x percent (expressed as a decimal) x time (years)
So 15,000(0.0525)2
Work from there :)

Answer 2

Ill show you step by step.

This is what the equation should look like 

Y=Initial value(1+/- Increasing or Decreasing value)^2 Which stands for time

$So Y=15,000(1+.0525)^2$

So you need to do 1.0525 to the 2nd power Which equals 1.10775625

So now you need to do 15,000(1.10775625)
