Question

Toni needs a total of $600 to buy a cell phone. She has already saved $350. If she saves $40 a week from her earning what is the least number of weeks she must work to have enough money to buy the cell phone?

Answer 1

First subtract 350 from 600 to get 250. I then divided by 40 to see how many groups were in 250, and got 6.25. Since it took greater then six days, Toni will have to work 7 days to get $600.
