Question: Lloyd, Mark, and Michael have their Pokemon cards collection. Currently, Mark has thrice as many cards as Lloyd but has 10 fewer cards than Michael. If Michael has 100 cards now, how many more cards should they collect so that all three of them will have a total of 300 cards?
Answer: Step-by-step reasoning process: Mark has 10 fewer cards than Michael so Mark has 100 cards - 10 cards = 90 cards. So, Lloyd has 90 cards / 3 = 30 cards. All three of them have 90 cards + 30 cards + 100 cards = 220 cards. Thus, they need to collect 300 cards - 220 cards = 80 more cards.
So the answer is 80.

Question: Gargamel needed new tires for his truck. He went to the auto shop and bought 4 tires on sale for $75 each. The salesman told him that he saved a total of $36. If Gargamel saved the same amount on each tire, what was the original price of each tire?
Answer: Step-by-step reasoning process: Gargamel saved $36 for all four tires, so to find the savings per tire was $36 / 4 = $9 saved per tire. Adding the savings to the discount price, the original price was $75 + $9 = $84.
So the answer is 84.

Question: Mary and Rose went shopping to buy presents. They spent the same amount. Mary bought two pairs of sunglasses for $50 each and a pair of jeans for $100. Rose bought a pair of shoes at $150 and two decks of basketball cards. How much did one deck of basketball cards cost?
Answer: Step-by-step reasoning process: Two pairs of sunglasses costs 2 x $50 = $100. So, Mary spent $100 + $100 = $200. Thus, two decks of basketball cards costs $200 - $150 = $50. Therefore, one deck of basketball cards costs $50 / 2 = $25.
So the answer is 25.

Question: Ali is collecting bottle caps. He has 125 bottle caps. He has red ones and green ones. If he has 50 red caps, what percentage of caps are green?
Answer:
Step-by-step reasoning process: He has 75 green caps because 125 - 50 = 75. The proportion of caps that are green is .6 because 75 / 125 = .6. The percentage that are green is 60 because .6 x 100% = 60%.
So the answer is 60.
