Question: 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.
Answer: 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.
