He needs 12 / 6 = 2 rungs per foot. So he needs 50 * 2 = 100 rungs. Each rung is 18 / 12 = 1.5 feet. So he needs 1.5 * 100 = 150 feet.
The answer: 150

Moksi took DJ Snake and his fiancee to a luxurious hotel for two nights at $4000 per night, for a total of 2 * $4000 = $8000. If Lil Jon also bought them a car worth $30000, the value of the treats from Lil John and Moksi summed up to $8000 + $30000 = $38000. Wynter presented them with a house worth four times the value of the car Lil Jon bought them, a total of 4 * $30000 = $120000. The total value of all the treats DJ Snake received on his engagement day is $120000 + $38000 = $158000.
The answer: 158000

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.
The answer: 9492
