$ 1 interest

P = (Po*r*t) / (1(1+r)^t).
P = Principal after 5 yrs.
Po = $42,600 = Initial Principal.
r = (2.9%/12) / 100% = 0.0024167 = Monthly % rate expressed as a decimal.
t = 12Comp./yr * 5yrs = 60 Compounding
periods.
P=(42600*0.0024167*60) /(1(1.0024167)^60) = $45,814.52.
Monthly = P/t = 45814.52 / 60 = $763.58
Int. = P  Po =
