Answer the following question.
A state fair charges $5 for a ticket. Two-thirds of the people who buy a ticket will buy deep-fried fair food for $8, one quarter will go on a ride for $4, and one eighth will spend $15 on a souvenir. The fair made $2520 from tickets. How many dollars did they make in all?
Step-by-step reasoning process: The fair made $2520 from tickets, so they had 2520 / 5 = 504 people attend the fair. Two - thirds of those people will buy food, so 504 * 2 / 3 = 336 people will buy food. The fair will make 336 * 8 = $2688 from food. A quarter of the people will go on a ride, so 504 / 4 = 126 people will go on a ride. The fair will make 126 * 4 = $504 from rides. An eighth of the people will buy a souvenir, so 504 / 8 = 63 people will buy souvenirs. The fair will make 63 * 15 = $945 from souvenirs. In all, the fair will make 2520 + 2688 + 504 + 945 = $6657.
The answer is 6657.

Answer the following question.
Ian won $100 in the lottery. He decided to use the money to pay off debts. He paid $20 to Colin. He then paid twice as much to Helen, as he had paid to Colin. Then finally, he paid half as much to Benedict, as he had paid to Helen. How much money, in dollars, does he have left after paying off debts?
Step-by-step reasoning process: Starting with $100, he paid $20 to Colin, leaving him with $100 - $20 = $80. Twice as much as $20 is 2 * $20 = $40. Thus, he paid $40 to Helen, leaving him with $80 - $40 = $40. Half as much to Benedict as he had paid to Helen is $40 / 2 = $20. Thus, he paid $20 to Benedict, leaving him with $40 - $20 = $20 after paying off all debts.
The answer is 20.

Answer the following question.
Diana earned $150 in July. She earned 3 times this amount in August. In September, She earned twice the money she earned in August. How much money did Diana earn over these three months?
Step-by-step reasoning process: The amount of money Diana earned in August is 3 * $150 = $450. The amount of money Diana earned in September is 2 * $450 = $900. The total amount of money Diana earned over the three months is $150 + $450 + $900 = $1500.
The answer is 1500.

Answer the following question.
Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples. Barry can reach apples that are 5 feet high. Larry is 5 feet tall, but his shoulder height is 20% less than his full height. If Barry stands on Larry's shoulders, how high can they reach?
Step-by-step reasoning process: Larry's shoulder height is 20% less than 5 feet, or 0.2 * 5 = 1 foot less than 5 feet. One foot less than 5 feet is 5 - 1 = 4 feet. If Barry stands on Larry's shoulders, they can reach 4 + 5 = 9 feet.
The answer is 9.
