X = number of adult tickets
7x = value of the adult tickets
3x = number of child tickets
3x * 3 = value of children's tickets, which is also 9x
Value of adults plus value of children's = 6000
7x + 9x = 6000
Combine terms
16x = 6000
Divide by 16
x = 6000/16
Simplify fraction
x = 3000/8 = 1500/4 = 750/2 = 375 = number of adult tickets
Number of children's tickets = 3 * 375 = 1125 = number of children's tickets
Check:
Adults = 375 * 7 = 2625
Children's = 1125 * 3 = 3375
Total = 6000
<span>on average, each ear of corn gives 3/4 a cup of corn. A large movie bag of popcorn has roughly 22 cups of corn. Therefore, there are about 29.333 cobs in a large bag of popcorn.</span>
If a cup is a regular sized cup that is 2 deciliters, and 1 liter equals 10 deciliters, that means that 1 liter = 5 cups, which means that 3 liters = 15 cups. If it is a cup that has 0.33 dl, then the correct number would be 9 cups.
