Question: Naomi is doing the wash. First she makes piles of different types, with one pile for towels, one for sheets, and one for clothes that need to be washed on the gentle cycle. The clothes take 30 minutes to wash. The towels take twice as long as the clothes to wash. The sheets take 15 minutes less time to wash than the towels. How many minutes total will it take for Naomi to wash everything?
Answer: The clothes take 30 minutes to wash and the towels take twice as long, 30 x 2 = 60 minutes to wash the towels. The sheets take 15 minutes less than the towels, 60 - 15 = 45 minutes to wash the sheets. It takes 30 minutes + 60 minutes + 45 minutes = 135 minutes to wash everything. The answer is 135.
[Question]The sum of the ages of Jeremy, Sebastian and Sophia in three years is 150. Currently, Sebastian is 4 years older than Jeremy. If Jeremy's age is 40, calculate Sophia's age three years from now?
[Answer]The age of Jeremy three years from now will be 40 + 3 = 43 years. Since Sebastian age is four years more than Jeremy's, Sebastian is currently 40 + 4 = 44 years. In three years, Sebastian will be 44 + 3 = 47 years old. The total age of Jeremy and Sebastian in three years will be 47 + 43 = 90. If the total age of Jeremy, Sebastian and Sophia in three years is 150, then Sophia's age in three years will be 150 - 90 = 60. The answer is 60.
Q: Reynald is the head of the varsity department, and he bought 145 balls. Twenty were soccer balls. There were five more basketballs than the soccer balls. Twice the number of soccer balls were tennis balls. There were ten more baseballs than the soccer balls, and the rest were volleyballs. How many were volleyballs?
A: There were 20 + 5 = 25 basketballs. There were 2 x 20 = 40 tennis balls. And, there were 20 + 10 = 30 baseballs. So, there were 20 + 25 + 40 + 30 = 115 soccer balls, basketballs, tennis balls and baseball altogether.                      Therefore, Reynald bought 145 - 115 = 30 volleyballs,. The answer is 30.
Question: It takes 30 minutes to make pizza dough and another 30 minutes in the oven for the pizza to cook. If one batch of pizza dough can make 3 pizzas but the oven can only fit 2 pizzas at a time, how many hours would it take for Camilla to finish making 12 pizzas?
Answer: Camilla needs 12 / 3 = 4 batches of pizza dough. 4 batches of pizza would require 30 x 4 = 120 minutes. Camilla needs to bake the pizzas 12 / 2 = 6 times. 6 times in the oven would take 30 x 6 = 180 minutes. Altogether, it would take 120 + 180 = 300 minutes to finish making 12 pizzas. 300 minutes is 300 / 60 = 5 hours. The answer is 5.
[Question]Nina has two pairs of shoes. She bought one of them for $22, and the second one was 50% more expensive. How much did Nina pay for both pairs of shoes?
[Answer]The second pair of shoes was 50 / 100 * 22 = $11 more expensive. That means that the second pair's price was 22 + 11 = $33. So for both pairs of shoes, Nina paid 33 + 22 = $55. The answer is 55.
[Question]Cynthia has three children whose ages add up to 35. Matthew is two years older than Rebecca and four years younger than Freddy. How many years old is Freddy?
[Answer]
Let A be Matthew’s age. Rebecca is A - 2 years old. Freddy is A + 4 years old. Their ages add up to 35, so A + A - 2 + A + 4 = 3A + 2 = 35. Therefore, 3A = 35 - 2 = 33. Matthew is A = 33 / 3 = 11 years old. Thus, Freddy is 11 + 4 = 15 years old. The answer is 15.
