Question: Jason has a moray eel that eats 20 guppies a day and 5 betta fish who each eat 7 guppies a day. How many guppies per day does she need to buy?
Answer: Step-by-step reasoning process: First find the total number of guppies the betta fish need: 5 fish * 7 guppies / fish = 35 guppies. Then add the number of guppies the eel needs to find the total number needed: 35 guppies + 20 guppies = 55 guppies.
So the answer is 55.

Question: Jeff bought 6 pairs of shoes and 4 jerseys for $560. Jerseys cost 1/4 price of one pair of shoes. Find the shoe's price total price.
Answer: Step-by-step reasoning process: Let X be the shoe price. The jersey's price is 1 / 4 * X. Jeff bought 6 pairs of shoes and 4 jerseys for 6 * X + 4 * (1 / 4X) = $560. Multiplying through the parentheses produces 6X + X = $560. Combining like terms produces 7X = $560. Dividing both sides by 7 produces X = $80, so the shoe price is $80. Since Jeff bought 6 pairs of shoes, he spent 80 * 6 = $480 on shoes.
So the answer is 480.

Question: In eight years, Mr. Bernard will be 3 times as old as Luke is now. If Luke is 20, what is 10 years less than their average age?
Answer:
Step-by-step reasoning process: If Luke is 20, he will be 20 + 8 = 28 years old in eight years. In eight years, Mr. Bernard will be 3 times as old as Luke is now, a total of 3 * 20 = 60 years old. Mr. Bernard is now 60 - 8 = 52 years old. The sum of their current ages is 52 + 20 = 72. Their average age is 72 / 2 = 36. 10 less than their average age is 36 - 10 = 26 years.
So the answer is 26.
