Answer:
325 hamburgers were sold on Tuesday
Explanation:
We can start solving the problem by using algebra. Let H be the number of hamburgers sold and C be the number of cheeseburgers sold. We know from the problem that:
H + C = 713 (total number of hamburgers and cheeseburgers sold)
C = H + 63 (there were 63 more cheeseburgers sold than hamburgers)
We can substitute the second equation into the first equation:
H + (H + 63) = 713
2H + 63 = 713
2H = 650
H = 325
