(a) how much money did jada receive?
(b) how much more money did nicholas receive than calvin?

  • Math -

    J+Nk+Ni+C=60
    J=1/2 (Nk+Ni+C)
    Nk=2/3 (Ni+C)
    Ni=3C

    take first equation,put second in it.

    3/2 Nk + 3/2Ni+3/2C=60
    or Nk+Ni+C=40

    Then J=20*****

    Now take
    Nk=2/3 (Ni+C)
    Ni=3C
    to get Nk=2/3(4C=8/3 C
    But 20=1/2 (Nk+Ni+C) or
    40=8/3 C + 3C + C so figure C...
