Question: During his summer break, Luke catches 2 fish every day for 30 days. If each fish gives him 2 fillets, then how many fish fillets does he have?
Answer: Step-by-step reasoning process: He catches 2 fish every day for 30 days so he catches 2 * 30 = 60 fish. Each fish yields 2 fillets so he has 2 * 60 = 120 fish fillets.
So the answer is 120.

Question: Marcus spends 20 minutes giving his dog a bath and half as long blow-drying her. Then he takes her for a walk along a 3-mile trail. If Marcus walks at 6 miles per hour, how much time does he spend with his dog total?
Answer: Step-by-step reasoning process: First find the total amount of time Marcus spends blow - drying his dog: 20 minutes / 2 = 10 minutes. Then find the time Marcus spends walking: 3 miles / 6 miles / hour = .5 hours. Then convert that time to minutes: .5 hours * 60 minutes / hour = 30 minutes. Then add up the time Marcus spends washing, drying and walking to find the total time: 10 minutes + 20 minutes + 30 minutes = 60 minutes.
So the answer is 60.

Question: Jason and Jeremy want to paint their wall white and agreed to split the cost of the paint. A gallon of paint costs $45 and can cover up to 400 square feet. How much will each of them contribute to the cost of the paint if their walls have a total area of 1600 square feet and will need a second coat?
Answer: Step-by-step reasoning process: They need 1600 square feet / 400 square feet / gallon = 4 gallons of paint for their walls. Since they will do a second coating, then they would need 4 gallons x 2 = 8 gallons in all. Eight gallons of paint will cost $45 / gallon x 8 gallons = $360. Thus, Jason and Jeremy will each contribute $360 / 2 = $180.
So the answer is 180.

Question: In mid-May, the depth of a river in Moreland is measured. By mid-June, the river is 10 feet deeper than mid-May. By mid-July, the river is three times deeper than mid-June. If the river is 45 feet deep in mid-July, how many feet deep was the river in mid-May?
Answer:
Step-by-step reasoning process: In mid - June, the river is 45 / 3 = 15 feet deep. In mid - May, the river was 15 - 10 = 5 feet deep.
So the answer is 5.
