Answer:
The answer is approx 75 months.
Step-by-step explanation:
We have P = 3000
r = 14%
Monthly payment = $60
We will use the formula :
Solving this we get n = approx 75 months. After 75 months few dollars will be left. And in the 76th month the balance will become negative.
For easy and better understanding, I have attached an excel sheet.
w+2x=16 ⇒ w=16-2x
x+2w=14 x+2(16-2x)=14
x+32-4x=14
-3x=14-32
-3x=-18 /:(-3)
x=6
w=16-2x=16-2·6=16-12=4
2y+w=-6 ⇒ 2y+4=-6
2y=-6-4
2y=-10 /:2
y=-5
