Basic Math Word Problem I Need Help With Please!

  1. Jul 31, 2006 #1
    Hello,
    I would love to get help or a formula to help figure out my son's word problem he arrived with this afternoon for Homework on his first day back to school here in Georgia.

    The problems is:

    Tim ate 100 cookies in 5 days. Each day he ate 6 more than he did the day before.
    How many cookies did he eat on the 1st day?

    Please help me help my son solve this problem.
    Thanks,
    Pat

    Hi there,

    Each day Tim eats six more cookies than the previous one.

    Let x = the number of cookies Tim ate on the first day
    x+6 = 2nd day
    x+12 = 3rd day
    x+18= 4th day
    x+24 = 5th day

    x + (x+6) + (x+12) + (x+18) + (x+24) = 100
    5x + 60 = 100

    Your son should be able to figure it out from there. Solve that equation and that's your answer. Make sense?
