Answer:
7 crayons in each pack
Step-by-step explanation:
1. subtract the 3 found crayons from the total (24)
24-3 = 21
2. divide 21 by 3 packs
21/3 = 7
35a + 25c = 2660
a = 2c
35(2c) + 25c = 2660
70c + 25c = 2660
95c = 2660
c = 2660/95
c = 28 <=== there were 28 children tickets
a = 2c
a = 2(28)
a = 56 <== there were 56 adult tickets
