Question

You discover that every month that you make a loan payment on time, your credit score goes up 3 points. You want to raise your score from 640 to 700. How many months will it take you?

Answer 1

So you still have 60 points to go up. Every month is 3 more points. Divide 60 by 3 which will give you the number of months left before you reach your goal. 60/3= 20 months or 1 year and 8 months.

Answer 2

It will take you 20 months to raise you score. 

The difference between 640 and 700 is 60, divide 60/3=20.
Hope this helps!
