B had 30% as many stamps as C. C had 125% as many stamps as D. If D gave B 70 stamps, B would then have 50% of what C had. How many stamps did the 3 of them have altogether?

  • math -

    B = .3C
    C = 1.25D
    B+70 = .5C

    We end up with

    B = 105
    C = 350
    D = 280

    Check:
    B+70 = 175 = 350/2

    SO, B+C+D=735
