You have to pay 29 a month until you reach 850 how many months will that take.

Let m be the number of months. We set up the inequality:
29m > = 850 <-- We want to know when we meet or exceed 850, so we use greater than or equal to

Type this inequality into our search engine, and we get:
m >= 29.31

We round up to the next integer month, to get m = 30.
