The repayment = 151 + debt x the interest rate of the period (monthly).
The debt = cost - the cash paid down = 5495 - 1000 = 4495
The interest rate of the period ( 12 months a year) = 0.28 divided by 12 = 0.28 / 12
The first repayment = 151 + debt x the interest rate of the period.
= 151 + 4495 x 0.28 / 12
= 151 + 104.86
= 255.88
