Jamie is opening a lemonade stand. She plans to sell two sizes of lemonade: small and large. The small lemonade costs $2, while the large lemonade costs $5. Jamie estimates that she will sell 3 times as many small lemonades as large lemonades.
After a weekend of selling, Jamie sold a total of 84 lemonades. How much money did Jamie make in total from selling the lemonades?
