First lets get rid of the deposit.
(0.956000)=5700
Formula is I=PRT
I= Interest earned
P=Principal amount (5700)
R=Rate (18% or 0.18 or 18/100)
T=Time period (2 years)
Equation:
I= 57002*0.18
I= 2052
But remember the question asks for monthly payments!
2052/24 (12 months in a year and T= 2 years)
Answer=$85.50
