Carmen initially has money in her bank account. Each week she withdraws the same amount of money from her account. Write an equation that relates b, her account balance after w weeks.

Carmen's balance after w weeks will be

Step-by-step explanation:

Let the initial money in Carmen's bank account be = x

Her account balance be denoted with b,

the number of weeks be = w

Let the amount withdrawn per week be = y

After one week, If Carmen withdraws some money, the money left in the account will be

b = x-y

After week two, the money left will be

b = x-y-y

After week three, the money left will be

b= x-y-y-y

We are beginning to notice a trend here, that the amount of money left in the account, is constantly reducing by y every week.

After w weeks, the money taken will be weeks = weeks.

Therefore, Carmen's balance after w weeks will be
