What would my final balance be if i put $650 in the bank for 60 months with an interest rate of 6%

$650 × 1.06 = $689
this is assuming that it is a simple interest rate
---------------------------

Assuming apr is the rate: 60÷12=5 (years)

650÷60=(per month)

Year one: ×12=130 (per annum) 
                130×1.06= $137.8

Year two: 137.8 + 130 = 267.8
                267.8×1.06 = 283.868

Year three: 283.868+130 = 413.868
                   413.863 × 1.06 ≈ $438.7

Year four: 438.7 + 130 = 568.7
                 568.7×1.06 ≈ $602.82

Year five: 602.82+130=732.82
                732.82×1.06 ≈ $776.79

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)
