  1. Henry = Base Amount. Ann=Henry+250. Joe=Henry+250+375. 250+250+375=875. 2000-875=1125. 1125/3=375. Base Amount=375. Henry=375. Ann=375+250=625. Joe=375+250+375=1000. Henry raised $375, Ann raised $625, and Joe raised $1000. Ratio= 3:5:8

  2. Hello.

    The amount of money Henry raised was $375.
    To find this, I used trial and error. I estimated that it would be around $300 - $400 , so I just started from $300 and went up (while also finding Ann and Joe's, making sure it would all equal to $2000).
    Eventually I came up with $375.

    Henry - $375
    Ann - (Henry + $250) $625
    Joe - (Ann + $375) $1000
    = $2000

    So the ratio was:
    375:250:1000
    which I simplified to
    3:5:8 (by dividing)

  3. Hello!

    So far, we know that
    Joe has 375 more than Ann
    Joe has 625 more than Henry (375 + 250)
    Ann has 250 more than Henry
    They all collected $2000.00 total.

    If we add 625 and 375 together we get 1000.
    *1000 is the remaining amount*

    And since Joe has 375 more than Ann and 625 more than Henry,
    Joe = 1000, Ann = 625, Henry = 375
    (1000 - 375) (1000 - 625)

    SINCERELY,
    Justin, Jatin, John *That's our 2 cents*

  4. Great job! I like when we get to see the use of two different methods to solve the same problem. And yes, the correct answers were: $375, $625, and $1000, respectively.
