Answer:
16 months
Step-by-step explanation:
First I will subtract how much he has already paid.
6000 - 3200 = 2800.
Now to find how many months it will take to get a total of 2800 dollars we must divide.
= 16
this means that an additional 16 months will be needed to reach the total of 6000 dollars.
Hope this helps! :)
