Katerina purchases 3 pots and 4 pans at the home goods store. Each pot costs $20. The total cost of Katerina's items is $100. If each pan is the same price, what is the cost of 2 pans? Give the rationale and then the answer.
Let's think step by step. The cost of the pots is 3 * $20 = $60. The cost of 4 pans is $100 - $60 = $40. Since each pan is the same price, the cost of 1 pan is $40 / 4 = $10. The cost of 2 pans is $10 + $10 = $20.. The answer is: 20.

Greg is riding his bike around town and notices that each block he rides, his wheels rotate 200 times. He's now on a a trail and wants to make sure he rides at least 8 blocks. His wheels have already rotated 600 times, how many more times do they need to rotate to reach his goal? Give the rationale and then the answer.
Let's think step by step. They need to rotate 1,600 times because 8 x 200 = 1,600. They need to rotate 1,000 more times because 1,600 - 600 = 1,000.. The answer is: 1000.

Amy is collecting candy for the car pool. She has 5 chocolate bars, 7 times as many M&Ms as chocolate bars, and 6 times as many marshmallows as M&Ms. Amy then arranges the candies into baskets. If she fills each basket with 10 candies, how many baskets will Amy fill? Give the rationale and then the answer.
Let's think step by step. Amy has 5 * 7 = 35 M&Ms. Amy has 35 * 6 = 210 marshmallows. Amy has 5 + 35 + 210 = 250 candies. She fills 250 / 10 = 25 baskets.. The answer is: 25.
