When visiting friends in a state that has no sales tax, two families went to a fast-food restaurant for lunch. The Browns bought 4 cheeseburgers and 3 medium fries for $16.53. The Greens bought 5 cheeseburgers and 4 medium fries for $21.11. Using c for the cost of a cheeseburger and f for the cost of medium fries, write a system of equations that models this situation. The Greens said that since their bill was $21.11, each cheeseburger must cost $2.49 and each order of medium fries must
cost $2.87 each. Are they correct?Justify your answer. Using your equations, algebraically determine both the cost of one cheeseburger and the cost of one order of medium fries.
