Question: Jonah bought 6 pineapples for $3 each. Each pineapple could be cut into 12 pineapple rings. He sold 4 pineapple rings for $5 each. How much profit did Jonah make?
Answer with step-by-step thinking: Jonah spent 6 x $3 = $18. He made a total of 6 x 12 = 72 pineapple rings. He sold 72 / 4 = 18 sets of pineapple rings. He made 18 x $5 = $90. His profit was $90 - $18 = $72.
So the answer is 72.

Question: If Lucy would give Linda $5, Lucy would have the same amount of money as Linda. If Lucy originally had $20, how much money did Linda have at the beginning?
Answer with step-by-step thinking: After giving $5, Lucy has $20 - $5 = $15 left. Since Linda has $15 after receiving $5, then she had $15 - $5 = $10 at the beginning.
So the answer is 10.

Question: Eighty-five cans were collected. LaDonna picked up 25 cans. Prikya picked up twice as many times as many cans as LaDonna. Yoki picked up the rest of the cans. How many cans did Yoki pick up?
Answer with step-by-step thinking:
LaDonna = 25 cans. Prikya is twice as many as LaDonna = 2 * 25 = 50. Yoki picked up the rest 85 - 25 - 50 = 10. Yoki picked up 10 cans.
So the answer is 10.
