Ethan is buying food for a picnic. He buys 8 hamburgers and 5 veggie burgers for a total of $13.50. Later he finds out that more people are coming and buys 7 hamburgers and 8 veggie burgers for a
total of $17.25. So that people can pay him back, he wants to know how much 1 hamburger costs
and how much 1 veggie burger costs. He writes down the following equations, in which h represents
the cost of one hamburger and v represents the cost of one veggie burger:
8h + 5y = 13.50
7h+ 8y = 17.25
Help Ethan figure out the cost of one hamburger and one veggie burger.
