When three friends sold their video games, Ryan, the first of the three friends, received $50 more than Jason from his sales. Jason received 30% more money than Zachary from selling his video games. If Zachary sold 40 games at $5 each, calculate the total amount of money the three friends received together from the sale of the video games. Give the rationale and then the answer.
Let's think step by step. The total amount of money that Zachary received from selling his video games is $40 * 5 = $200. Jason received 30 / 100 * $200 = $60 more than the amount Zachary received after selling his games. The total amount of money that Jason received is $60 + $200 = $260. Together, Zachary and Jason received $260 + $200 = $460 from the sale of their video games. Ryan received $260 + $50 = $310 from the sale of his video games. The three friends made a total of $310 + $460 = $770 from the sale of the video games.. The answer is: 770.

James takes 20 units per semester at community college. If each unit costs $50 how much does he pay for 2 semesters? Give the rationale and then the answer.
Let's think step by step. He pays 20 * 50 = $1000 per semester. So he pays 1000 * 2 = $2000.. The answer is: 2000.

Anton has three times as many cards in his collection as Heike does. Ann has six times as many cards as Heike does. If Ann has 60 cards, how many more cards does Ann have more than Anton? Give the rationale and then the answer.
Let's think step by step. If Ann has 60 cards, which is six times as many cards as Heike, Heike has 60 / 6 = 10 cards. Anton has three times as many cards in his collection as Heike does, and since Heike has 10 cards, Anton has 10 * 3 = 30 cards. Ann has 60 - 30 = 30 more cards than Anton.. The answer is: 30.
