lyle needs 200g of chocolate that is 86% cocoa for a cake recipe he has one kind that is 99% cocoa and another kind that is 70% cocoa. How much of each kind does he need to make the cake

  • math - ,

    g = grams of 99% cocoa
    0.99g = value of 99% cocoa
    200 - g = grams of 70% cocoa
    0.70(200 - g) = value of 70% cocoa
    0.86(200) = value of mixture

    0.99g + 0.70(200 - g) = 0.86(200)

    Solve for g, grams of 99% cocoa
    200 - g = grams of 70% cocoa
