First-grade student, Noah, has set up a lemonade stand in his front yard. It cost $10 for the initial supplies, and it costs him $0.05 for each cup of lemonade he makes. He is selling his lemonade for $0.50 per cup. How
many cups of lemonade must Noah sell in order to not lose any money? Write a system of linear equations
that models Noah's expenses and revenue. Let c represent the number of cups of lemonade sold, and let y
represent the total expenses or total revenue.
