The number of customers who buy in the second week is 35 customers * 2 = 70 customers. The number of customers who buy in the third week is 35 customers * 3 = 105 customers. The total number of customers who buy during the 3 weeks is 35 customers + 70 customers + 105 customers = 210 customers. The total commission he receives is 210 customers * $1 / customer = $210. The total income he earns is $210 + $500 + $50 = $760.
The answer: 760
Reverse engineering the question: Julio receives a $1 commission for every customer that buys in Edgars Fashion Store. The store sells to 35 customers in the first week, twice as many in the second week, and triple as many as the first week in the third week. If he receives a salary of $500 for the 3 weeks and a bonus of $50, how much in total does he earn for the 3 weeks?


Reasoning and answer: Let X be my age now. In ten years, I'll be X + 10 years old. In ten years, my brother will be (X + 10) * 1 / 2 years old. In ten years, (X + 10) + (X + 10) * 1 / 2 = 45. So (X + 10) * 3 / 2 = 45. X + 10 = 45 * 2 / 3 = 30. X = 30 - 10 = 20 years old.
The answer: 20
What was the question?
Question: In ten years, I'll be twice my brother's age. The sum of our ages will then be 45 years old. How old am I now?


He eats 32 from the largest pizzas because 2 x 16 = 32. He eats 16 from the small pizza because 2 x 8 = 16. He eats 48 pieces because 32 + 16 = 48.
The answer: 48
Reverse engineering the question: Albert is wondering how much pizza he can eat in one day. He buys 2 large pizzas and 2 small pizzas. A large pizza has 16 slices and a small pizza has 8 slices. If he eats it all, how many pieces does he eat that day?


Reasoning and answer: The Saturday morning exodus out of the park comprised 4 * 2880 = 11520 elephants. This means that after the exodus, the park was left with 30000 - 11520 = 18480 elephants. Since the final number of elephants was 28,980, the new elephants that entered were 28980 - 18480 = 10500. The rate at which the new elephants entered the park was therefore 10500 / 7 = 1500 elephants / hour.
The answer: 1500
What was the question?
Question: Utopia National Park hosted 30,000 elephants on Friday night. The next morning, there was a 4-hour elephant exodus out of the park, at a constant rate of 2,880 elephants/hour. Over the next 7-hour period, new elephants entered the park at a constant rate. If the final number of elephants in the park was 28,980, at what rate did the new elephants enter the park?


Santino has 2 * 10 = 20 papaya fruits. Santino has 3 * 20 = 60 mango fruits. In total, Santino has 20 + 60 = 80 fruits.
The answer: 80
Reverse engineering the question: Santino has 2 papaya trees and 3 mango trees. If each papaya tree produces 10 papayas and each mango tree produces 20 mangos, how many fruits does Santino have in total?


Out of the 40, 40 x 1 / 10 = 4 students are absent. So, 40 - 4 = 36 students are present in school. Out of the 36, 36 x 3 / 4 = 27 students are in the classroom. This means, 36 - 27 = 9 students are in the canteen.
The answer: 9
Reverse engineering the question:
There are 40 students in a class. If 1/10 are absent, 3/4 of the students who are present are in the classroom, and the rest are in the canteen, how many students are in the canteen?
