Question

Item 6 A savings account earns 5% simple interest per year. The principal is $1200. What is the balance after 4 years?

Answer 1

The formula for simple interest is

I=PRT

here P=$1200

R=5% or 0.05

T=4 years

plugging in the formula we get

I=1200*0.05*4=240

Balance after four years =1200+240=$1440
