Question

elena has 225 dollars in her bank account. She takes out 20 dollars each week. After w weeks she has d dollars left in her bank account.write and equation that represents the amount of money left in her bank account after w weeks?

Answer 1

Elena has $225 in her bank account.

She takes out (subtraction) $20 each week.

Let w represents weeks.

Let d represents dollars left in her bank account after w weeks.

Then the algebraic equation becomes

`d=225-20w`

Since Elena takes out $20 per week that is why 20w is subtracted from the total amount in her account that is $225
