solomonzelman · Answer

I was hoping for compound interest that would be more fun.

well, you have a simple interest rate x. This interest adds to the deposit every year (and the interest added stays the same).

$\large\color{black}{ \displaystyle 7500\times 3x =900}$

solomonzelman · Answer

3x has a coefficient 3, because it is an interest rate in 3 years.
x is the rate in decimal.

we are just going backwards here.

I thought you have to find the simple interest

anonymous · Answer

@HelpMePlease14 
$900 in 3yrs is $300/year so
A simple way to find the interest rate is take
$300/yr and divide it by 7500
300/7500=.04
turn that to a percent and you get 4%
