According to actuarial math, where interest is considered, he paid $7640, (you cannot simply add "monies" that are in different time slots on a time graph.

e.g. Making $40,000 in 1985 ≠ $40,000 in 2013

If you ignore interest the total he paid

= .2(7640) + 36(191.60) = $8425.60

A more interesting question would have been to find the interest rate per annum compounded monthly that he was charged.
