Question

You are putting money into a bank account. You start with $100 and add $12 every month. The total amount of money in your account can be represented by the following equation. (where T is total amount and M is the number of months):
T = 100 + 12 M

If you have $208, how many months have passed?

Show the equation and how you got the answer.

Answer 1

The answer would be 9 months. 9x12=108 so that would be 100+108= 208

Answer 2

100

Add 12 every month

Ex: 100 + 12

100 + 12 + 12+ 12+ 12+ 12+ 12+ 12+ 12+ 12

It wound not be 100 x 9 because 100 x 9 is 900

Therefore 9 months

9 x 12 = 108

so that would be 100+108= 208

Hope this helps~
