Rick and Jim are working at the concession stand at the school basketball game. Rick sells 13 more burgers than Jim.
The equation given below shows this relationship, where g represents the number of burgers Rick sells, and h represents the number of burgers Jim sells. If Rick sells 33 burgers, how many burgers does Jim sell?
g = 33, h = g - 13
h = 33 - 13
Jim sells 20 burgers.
