[Question]James paves a new parking lot. It is 400 feet by 500 feet. Only 80% of that is useable for parking. It takes 10 square feet to park a car. How many cars can be parked?
[Answer]The parking lot is 400 * 500 = 200,000. There are 200,000 * .8 = 160,000 square feet of parking space. That means he can park 16,0000 / 10 = 16000 cars. The answer is 16000.

[Question]A club with 30 members ordered fruit juices. Two-fifths of them ordered lemon juice. One-third of the remaining members ordered mango juice, and the rest ordered orange juice. How many members ordered orange juice?
[Answer]30 x 2 / 5 = 12 members ordered lemon juice. So, 30 - 12 = 18 members did not order lemon juice. Since 1 / 3 of the remaining ordered mango juice, then 18 x 2 / 3 = 12 members ordered mango juice. Therefore, 18 - 12 = 6 members ordered orange juice. The answer is 6.

Julio has 4 * 2 = 8 liters of orange soda. Julio also has 7 * 2 = 14 liters of grape soda. Julio therefore has a total of 8 + 14 = 22 liters of soda. The amount of orange soda that Mateo has is 1 * 2 = 2 liters of orange soda. In addition, Mateo has 3 * 2 = 6 liters of grape soda. In total, Mateo has 2 + 6 = 8 liters of soda. This means that Julio has 22 - 8 = 14 liters more of soda. The answer is 14.
