Question

At the motocross races, four hamburgers and six soft drinks cost $28, and three hamburgers and three soft drinks cost $18. Which system of linear equations below can be used to determine the price of a hamburger and the price of a soft drink?
Let x represent the cost of a hamburger, and let y represent the cost of a soft drink

A) 7x + 9y = 46

B) 4x + 6y = 28
3x + 3y = 18

C) 4x + 3y = 28
6x + 3y = 18

D) 4x + 3x = 28
6y + 3y = 18
