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?

Respuesta :

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: 4 months.

Step-by-step explanation:

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

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

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

[tex]765 = 135m+225\\\\\Rightarrow\ 135m=765-225\\\\\Rightarrow\ 135m=540\\\\\Rightarrow\ m=\dfrac{540}{135}=4[/tex]

Hence, you have $765 after 4 months.
