    Complete Question

    A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20 dozen?

    Answer:

    11 2/3 cups of flour

    Step-by-step explanation:

    From the above question:

    6 dozen = 3 1/2 cups of flour

    20 dozen = x

    Cross Multiply

    6 dozen × x = 20 dozen × 3 1/2 cups of flour

    x = 20 dozen × 3 1/2 cups of flour/6 dozen

    x = 20 × 7/2 /6

    x = 140/2 ÷ 6

    x = 140/2 × 1/6

    x = 140/12 cups of flour

    x = 11 8/12

    = 11 2/3 cups of flour

    Therefore, 11 2/3 cups of flour must be used to make 20 dozen.
