Nancy was trying to save up $457. at her job she made $8 an hour and she worked 40 hours a week. after paying for her food and other expenditures she ended up only saving 1/8 of her weeks earning. how much money did she save up each week.

So if she makes 8 and hour and works 40 hours a week
Thats 320 take home every week
Now divide that number by 8 as she is only taking home 1/8th and you are left with only 40 dollars saved a week.
Meaning to get to 457 it would take 11.425 weeks of work
