Question: Angus has $20 worth of tokens less than Elsa has. If Elsa has 60 tokens and each token is worth $4, how many tokens does Angus have?
Answer with step-by-step thinking: If each token is worth $4, then $20 worth of tokens is $20 / $4 = 5 tokens. Angus has 5 tokens less than Elsa who has 60 so Angus has 60 - 5 = 55 tokens.
So the answer is 55.


Question: Melissa bought 4 packs of tennis balls for $24 in total. Each pack contains 3 balls per pack. How much did it cost Melissa for each tennis ball?
Answer with step-by-step thinking: There are 4 packs of tennis balls while each pack has 3 balls. 4 * 3 = 12 balls. Melissa spent a total of $24 for a total of 12 balls. $24 / 12 = $2 per ball.
So the answer is 2.


Question: Ali, Peter, and Joey were fishing. The fish Ali caught weighed, in sum, twice as much as the fish that Peter caught. Joey caught 1 kg more fish than Peter. Together the three of them caught 25 kg of fish. How many kilograms did Ali catch?
Answer with step-by-step thinking:
Let x be the weight of the fish that Peter caught. Then Ali and Joey caught 2 * x and x + 1 kg of fish, respectively. So, x + 2 * x + x + 1 = 25. So, 4 * x = 25 - 1 = 24. So, x = 6. Therefore, Ali caught 2 * x = 2 * 6 = 12 kg of fish.
So the answer is 12.
