Hello!
Let's use 'x' to represent the cost of the burger, and 'y' to represent the cost of the hotdog.
2x + y = 482
× + 2y = 370
2x + 47 = 740
-3y = -258
y = 86 cents
2x + 86 = 482
2x = 396
x = 198
A burger costs $1.98 and a hot dog costs $.86
I hope this didn't confuse you, I'm not very good at explaining!
