Answer:
20%
Step-by-step explanation:
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
First, you must get rid of the fractions. You can do that by multiplying that 15. Then, you get:
45x-12=-5x
Then combine the like terms
50x=12
x=12/50=6/25
