In this problem, we need to find the length of an annuity. We already identified the interest rate, the PV, and the payments.
Using the PVA equation: PVA =C({1 – [1/(1 +r)t]} /r
$18,000 = $750{[1 – (1/1.019) t] / 0.019}
Then solve for t:
1/1.019t= 1 − {[($18,000)/($750)](0.019)}
1/1.019t= 0.544
1.019t= 1/(0.544) = 1.838
t= ln 2.193 / ln 1.019 = 32.34 months or 2.7 in years
