[Question]Sara is checking out two different stores to buy a computer. The first store offers a device for $950 with a 6% discount. The second sells the same computer for €920 with a 5% discount. What is the difference in price between the two stores?
[Answer]The amount of discount in the first store 950 x 6 / 100 = $57. So, the device costs 950 - 57 = $893 in the first store. The amount of discount in the second store is 920 x 5 / 100 = $46. So, the device costs 920 - 46 = $874 in the second store. The difference in price is 893 - 874 = $19. The answer is 19.
Q: Aida has twice as many dolls as Sophie, and Sophie has twice as many dolls as Vera. How many dolls do Aida, Sophie, and Vera have combined if Vera has 20 dolls?
A: If Sophie has twice as many dolls as Vera, then she has 2 * 20 dolls = 40 dolls. Aida has 2 * 40 dolls = 80 dolls, twice the number Sophie has. In total, they have 80 dolls + 40 dolls + 20 dolls = 140 dolls. The answer is 140.
Question: A tomato plant has 100 tomatoes. Jane picks 1/4 of that number for use in their house. After a week, she goes back and picks 20 more tomatoes, and the following week picks twice that number. What's the total number of fruits remaining on the tomato plant?
Answer: When she picks 1 / 4 of the number of tomatoes, she goes home with 1 / 4 * 100 = 25 tomatoes. The total number of tomatoes remaining will be 100 - 25 = 75 tomatoes. After picking 20 more tomatoes the following week, the number of tomatoes remaining is 75 - 20 = 55 tomatoes. The next week she picks twice the number she picked the previous week, that is 20 * 2 = 40 tomatoes. The total number of tomatoes remaining after the final picking is 55 - 40 = 15 tomatoes. The answer is 15.
