Answer:
16 months
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.
![2800 / 175](https://img.qammunity.org/2021/formulas/mathematics/high-school/z8rq3c2wzwu9ecgf3o7o11path47xr36aj.png)
= 16
this means that an additional 16 months will be needed to reach the total of 6000 dollars.
Hope this helps! :)
