Respuesta :

-10w - 400 = o

w= weeks
o = new outstanding balance

Answer:

[tex]400-10w[/tex].

Step-by-step 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Since the with-drawl amount is $10 per week, so amount withdrawn in w weeks would be [tex]10w[/tex].

The amount left after w weeks would be $400 minus [tex]10w[/tex].

Therefore, our required expression would be [tex]400-10w[/tex].
