P = $660, R = 9%, T = 2 years I = ?

((Honestly I don't understand anything, I was busy throwing up while my teacher was showing us how to do it))

$ 118.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

I = 660 × 0.09 × 2 = 118.8

I = $ 118.80

The simple interest accumulated

on a principal of $ 660.00

at a rate of 9% per year

for 2 years is $ 118.80.
