Q: Carol gets a fixed $20 allowance each week. She can also earn $1.5 more dollars each week if she does extra chores. At the end of 10 weeks, she has 425 dollars. How many extra chores did she average each week?
A: She earned $42.5 on average per week because 425 / 10 = 42.5. She earned $22.5 each week from extra chores because 42.5 - 20 = 22.5. She did 15 extra chores a week because 22.5 / 1.5 = 15. The answer is 15.
Question: Doc's Pizza contains 6 pieces of pizza. Ten fourth-graders each bought 20 pizzas from Doc's Pizza and put them in their box. How many pieces of pizza are the children carrying in total?
Answer: If Each fourth - grader bought 20 pizzas, with each pizza having 6 pieces, each fourth - grader had a total of 20 * 6 = 120 pieces of pizza in their box.

[Question]Bridgette and Alex are getting married. Bridgette is inviting 84 guests, and Alex is inviting two thirds of that number of guests. They hired a caterer to make a plated meal for each guest at the wedding reception. The caterer always makes ten extra plates just in case something goes wrong. Each plate of steak and asparagus in garlic butter will have 8 asparagus spears on it. How many asparagus spears will the caterer need in all?
[Answer]Alex is inviting 84 * 2 / 3 = 56 guests. Bridgette and Alex’s guests will need 84 + 56 = 140 plates. The caterer makes 10 extra plates, so they will need 140 + 10 = 150 plates. To put 8 asparagus spears on each plate, the caterer will need 150 * 8 = 1200 asparagus spears. The answer is 1200.

Question: Krystiana owns an apartment building. The rooms on the first floor cost $15 per month and the rooms on the 2nd floor cost $20 per month. The rooms on the third floor cost twice as much as the rooms on the first floor, but only two rooms are occupied. If each floor has 3 rooms, how much does Krystiana earn every month?
Answer: Krystiana earns $15 x 3 = $45 for the rooms on the first floor every month. She earns $20 x 3 = $60 for the rooms on the second floor every month. And the cost for each room on the third floor is $15 x 2 = $30. So, the total amount she earns for the rooms on the third floor is $30 x 2 = $60 every month. Therefore, the total amount she earns from the apartment building is $60 + $60 + $45 = $165. The answer is 165.
