5 - 15 __________ 10 _____20%
15 - 25 _________ 20 _____13%
25- 35 _________ 30 _____ 21%
35 - 45 _________40 _____ 17%

Answer:
17.6 ounces (U.S.) and or 2.2 cups (U.S.)
Step-by-step explanation:
88 ounces divided by 5 equals 17.6 ounces
88 / 5 = 17.6
The remainder can round the answer to 18 (five or more raise the score -- four or less let it rest) but the 88 ounce bag of popcorn will not be even if everyone gets 18 ounces of popcorn
If everyone were to get 18 then the bag a popcorn would have to have 90 ounces of popcorn in it
*Side note: 8 ounces is 1 cup
