You simply do the direct substitution,
you remove m and put the number of months given,
b=540-(30*9)= 270$
This example gives you an equation where calculates how much your balance is, an equation of b (balance) as a function of m (number of months), so simply substitute with the number of months given to you into the equation and you get the answer.
Hope this helps.

Step-by-step explanation:
<u>You just add up the numbers of different ways:</u>
Janet has remaining $ 149.16 in her paycheck
<h3><u>
Solution:</u></h3>
Given that Janet's paycheck was $248.60
She put 1/4 of her paycheck into a checking account
Therefore amount put into checking account is given as:
![\text {amount put into checking account }=\frac{1}{4} \times 248.60=62.15](https://tex.z-dn.net/?f=%5Ctext%20%7Bamount%20put%20into%20checking%20account%20%7D%3D%5Cfrac%7B1%7D%7B4%7D%20%5Ctimes%20248.60%3D62.15)
So she spent $ 62.15 into checking account
Now the remaining paycheck amount left is:
remaining paycheck amount left = 248.60 - 62.15 = 186.45
Therefore remaining paycheck amount left is $ 186.45
Now she spent 1/5 of what was left to buy dinner for her family
![\text { Amount spend on dinner }= \frac{1}{5} \times 186.45 = 37.29](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Amount%20spend%20on%20dinner%20%7D%3D%20%5Cfrac%7B1%7D%7B5%7D%20%5Ctimes%20186.45%20%3D%2037.29)
So she spent $ 37.29 on dinner
<u><em>Now the remaining paycheck amount left is:</em></u>
remaining paycheck amount left = 186.45 - 37.29 = 149.16
Thus Janet has remaining $ 149.16 in her paycheck
