Tricia is a third of Amilia's age and Amilia is a quarter of Yorick's age. Yorick is twice Eugene's age and Khloe is a third of Eugene's age. Rupert is 10 years older than Khloe but 2 years younger than Vincent who is 22 years old. How old, in years, is Tricia? Give the rationale and then the answer.
Let's think step by step. Rupert is younger than Vincent by 2 years, so he is 22 years old 2 years = 20 years old. Khloe is 10 years younger than Rupert so she is 20 years old 10 years = 10 years old. Eugene is 3 times older than Khloe so he is 10 years old * 3 = 30 years old. Yorick is twice Eugene's age so he is 30 years old * 2 = 60 years old. Amilia is a quarter of Yorick's age so she is 60 years old / 4 = 15 years old. Tricia is a third of Amilia's age so she is 15 years old / 3 = 5 years old.. The answer is: 5.

Sam is stocking up on canned tuna. He got 9 cans at the supermarket, and had 5 coupons for 25 cents off a single can per coupon. He paid $20 and got $5.50 in change. How many cents does a can of tuna cost? Give the rationale and then the answer.
Let's think step by step. His total without the coupons was $20 - $5.50 = $14.50. He had 5 coupons that each saved him 25 cents, so the full price of all the tuna is $14.50 + 5 * $0.25 = $15.75. He bought 9 cans of tuna, so each can costs $15.75 / 9 = $1.75. As 1 dollar has 100 cents 1.75 * 100 = 175 cents.. The answer is: 175.

Danny brings 3 watermelons to his family picnic. He cuts each watermelon into 10 slices. His sister brings 1 watermelon to the family picnic, and she cuts the watermelon into 15 slices. How many watermelon slices are there in total at the picnic? Give the rationale and then the answer.
Let's think step by step. From Danny, there are 3 * 10 = 30 watermelon slices. From his sister, there are 1 * 15 = 15 watermelon slices. There are a total of 30 + 15 = 45 watermelon slices.. The answer is: 45.
