Question: From Monday to Friday, Elle practices piano for 30 minutes. On Saturday, she practices piano three times as much as on a weekday. There is no practice on Sunday. How many hours does Elle spend practicing piano each week?
Answer: Step-by-step reasoning process: From Monday to Friday, Elle practices 0.50 x 5 = 2.5 hours. On Saturday, she practices 0.50 x 3 = 1.5 hours. Each week, Elle practices piano for 2.5 + 1.5 = 4 hours.
So the answer is 4.

Question: Jonah decided to set up an aquarium. He started with 14 small fish. He added 2 more, but they ate 6 of his original fish before he could remove them and take them back to the store. He exchanged them for 3 new fish. How many fish does Jonah have now?
Answer: Step-by-step reasoning process: Jonah started with 14 fish + 2 more = 16 fish. Of the 16 fish – 6 were eaten – 2 were returned to the store = 8 fish. After he returned the fish to the store, he exchanged them for 3 new fish + 8 fish that were left = 11 fish now in his tank.
So the answer is 11.

Question: Two puppies, two kittens, and three parakeets were for sale at the pet shop. The puppies were three times more expensive than the parakeets, and the parakeets were half as expensive as the kittens. If the cost of one parakeet was $10, what would it cost to purchase all of the pets for sale at the pet shop, in dollars?
Answer: Step-by-step reasoning process: Puppies cost three times more than parakeets, or 3 * $10 = $30 per puppy. Parakeets were half as expensive as the kittens, or 2 * $10 = $20 per kitten. Two puppies cost 2 * $30 = $60. Two kittens cost 2 * $20 = $40. And three parakeets cost 3 * $10 = $30. Thus, the cost to purchase all of the pets for sale at the pet shop is $60 + $40 + $30 = $130.
So the answer is 130.

Question: At the museum, Bethany saw 4 times more still lifes than portraits. If she saw 80 paintings total, how many portraits did she see?
Answer:
Step-by-step reasoning process: Let s be the number of still lifes Bethany saw and p be the number of portraits. We know that s + p = 80 and s = 4p. Substituting the second equation into the first equation, we get 4p + p = 80. Combining like terms, we get 5p = 80. Dividing both sides by 5, we get p = 16.
So the answer is 16.
