The latest IPhone came out and you HAVE to have it!!!! It cost $1999.00. You make 500 a week cash and need to give 200 of that to your parents. How long will it take you to buy the phone you want?
It takes that long, because since you get $500 and gets 200 taken away, you have 300 dollars every time you make money. So 1999.00 divided by 300 is 6.663333333333333.
