Question

Withdrawing $10 every week from an outstanding balance
of $400

Answer 1

400-10x. X is how many weeks

Answer 2

`400-10w`.

Explanation:

Let w represent the number of weeks.

We are supposed to write an expression for the given word phrase.

Since the with-drawl amount is $10 per week, so amount withdrawn in w weeks would be
`10w`.

The amount left after w weeks would be $400 minus
`10w`.

Therefore, our required expression would be
`400-10w`.
