I have a $9000 loan at 5% interest.
What monthly payment will let you pay off the loan in each amount of time?
a.) 36 months b.) 39 months c.) 48 months
:
It's pretty cumbersome equation, I don't pretend to understand it.
MP = where:
Mp = monthly payment
p = amt borrowed
r = interest rate/100
n = period per year
t = no. of yrs
IN this problem we will try to find nt
= 269.74
do the math
= 269.74
:
=
:
= 7.193
1.004167)^nt = 7.193(1.004167^nt - 1)
:
1.004167)^nt = 7.193(1.004167)^nt - 7.193
:
7.193 = 7.193(1.004167)^nt - 1(1.004167^nt)
:
7.193 = 6.193(1.004167)^nt
= 1.004167^nt
1.161467 = 1.004167^nt
nt =
:
nt = 35.996 ~ 36 months
