Question

The amount of money in your savings account after m months is represented by a = 135m+225. After how many months do you have $765 in your savings account?

Answer 1

4. $765 becomes your A value. So you then have 765=135m+225. Subtract 225 from both sides so you get 540=135m. Then divide 135 from both sides. This leaves you with 4=m.

Answer 2

Answer: 4 months.

Explanation:

Given : The amount of money in your savings account after m months is represented by
`a = 135m+225.`

To find : The number of months to have $765 in your savings account.

We put a=765 in the given equation, we get

`765 = 135m+225\\\\\Rightarrow\ 135m=765-225\\\\\Rightarrow\ 135m=540\\\\\Rightarrow\ m=(540)/(135)=4`

Hence, you have $765 after 4 months.
