Hi Alton, let H represent the number of hamburgers sold. Then H + 71 is the number of cheeseburgers sold. The total is 571.
Equation:
H + (H + 71) = 571
2H + 71 = 571
Subtract 71 from both sides:
2H = 500
Divide both sides by 2:
H = 250
Solution:
There were 250 hamburgers sold. There were 71 more cheeseburgers sold then hamburgers. There were 321 cheeseburgers on Sunday.
