Harry wants to build a homemade helium balloon with his son, Kevin, so he and Kevin go to the store with $200. They buy a giant sheet to turn into a balloon for $42, a rope for $18, and a propane tank and burner for $14. They plan to use the rest of the money on helium. The helium is $1.50 per ounce. For every ounce they buy, the balloon can fly 113 feet higher. How many feet up can they fly the balloon?
Please answer and provide answer explanation.
9492
They have $126 for helium because 200 - 42 - 18 - 14 = 126.

They can buy 84 ounces of helium because 126 / 1.

5 = 84.

They can fly 9,492 feet up because 84 x 113 = 9,492.

.

Therefore, the answer is 9492
