It will take her 8 weeks to save the money.

$100 - $70 = $30

$240 / $30 = 8

It is given in the question that, Anna makes $100 a week. She spends $70 a week and saves the rest.

So her weekly saving is

[tex] 100-70=$30 [/tex]

She is saving to buy a $240 sound system.

Let the numbr of weeks is x

So we have

[tex] 30x=240
\\
Dividing \ both \ sides \ by \ 30
\\
x = 8 [/tex]

So the correct option is the last option .
