Ms. Smith's class will participate in an Algebra-Thon to raise money for a class trip. The Algebra-Thon workbook has math problems. Students can raise money based on the number of math problems they answer correctly or by accepting a donation without regard to the number of math problems answered correctly. As shown in the table, prizes are awarded to students who raise or more. Benjamin, a student in the class, answers math problems correctly. His grandmother pays per correct answer. His uncle gives him a donation. 1. If Benjamin receives from his grandmother and uncle, how much money does his uncle give him? Explain. 2. Benjamin wants to win headphones. In addition to his grandmother and uncle, some friends of his agree that each one will give him a donation. Some other friends agree that each one will pay him for every correct answer. The number of friends who donate to Benjamin is times the number who pay him for correct answers. Write and solve an inequality to find the least number of friends who must pay him for each correct answer in order for Benjamin to meet his goal. Justify your answer.
