    Answer:

    Kyle filled  4 servings of 10oz   16 servings of 14 oz  9 servings of 20 oz

    Step-by-step explanation:

    10oz  95c = x

    14oz 1.15c = y

    20oz 1.50c = z

    444 given divided by 29 cups

    = 444/29 = 15.3103448 average cup weight so the higher size were used more.  

    9 servings of 20 oz cups = 180 = cost check at 1.50 x 9 = $13.50

    16 servings of 14 oz cups = 224 = cost check at 16 x 1.15 = $18.40

    4 servings of 10 oz cups = 40 = cost check at 4 x 0.95 = $3.80

    Where given collection total said to be $35.90 we total 13.5+18.4+3.8 = 35.7 so we are 0.20 out and can try again.

    OR just submit this.  4 servings of 10oz   16 servings of 14 oz  9 servings of 20 oz
