How many pounds of the soybeans meals should be in the mixture?______pounds

  • math -

    Try this.
    Let S = pounds of soy bean meal.
    Let C = pounds of corn meal.
    so one equation is
    S + C = 240

    The other equation is
    0.12S + 0.06S = 0.1*240
    Solve the two equations for the two unknowns.

  • math -

    so the answer would be
    s=44lbs
    c=4.09lbs
