A crayon weighs 1/2 ounce. There are 96 crayons in a box. The box weighs 4 ounces. How many pounds do 12 boxes of crayon weigh?

Answer:
39 pounds
Step-by-step explanation:
1) 1/2 + 1/2 = 1 -> this means 2 crayons equals 1 ounce
2) 96/2 = 48 -> 48 oz of crayons *oz means ounces*
3) 48 + 4 = 52 oz -> box + crayons = total weight of box of crayons
4) 52 * 12 = 624 oz
5) 624/16 = 39 lbs -> convert ounces to pounds
