Answer 1

Popcorn kernels in 1 lb bags.
4 ounces of kernels make two quartz of popped popcorn

Number of bag of kernels to fill ten gallons of popped popcorn.

1 pound = 16 ounces
16 ounces / 4 ounces = 4 
4 * 2 quarts = 8 quarts
8 quarts / 4 quarts per gallon = 2 gallons

1 pound bag of popcorn kernel produces 2 gallons worth of popped popcorn.

To make 10 gallons worth of popped popcorn, you need 5 1-pound bags of popcorn kernels.
