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?

How much money do they have left? ** They have $126 for helium because 200 - 42 - 18 - 14 = <<200-42-18-14=126>>126.
How many ounces of helium can they buy? ** They can buy 84 ounces of helium because 126 / 1.5 = <<126/1.5=84>>84
How many feet up can they fly the balloon? ** They can fly 9,492 feet up because 84 x 113 = <<84*113=9492>>9,492
