Suppose that you have a supply of a 25% solution of alcohol and a 75% solution of alcohol. How many quarts of each should be mixed to produce 100 quarts that is 30% alcohol?

  • MATH -

    .25x+.75(100-x)=.30(100)
    solve for x

    I solved for x which is 90. what do I do next ?

    thanks for your help

  • MATH -

    x=how many quart of 25% solution of alcohol
    100-x=the reminder of quart; or how many quart of 75% solution of alcohol
