Answer:
Step-by-step explanation:
We have to come up with a system of equations in order to solve this because we have 2 unknowns: hamburgers and cheeseburgers. h is hamburgers and c is cheeseburgers. We know that both of these together totaled 762, so
h + c = 762
We also know that more cheeseburgers were sold than were hamburgers. 62 more cheeseburgers, to be exact. So the second equation is
c = h + 62.
Now we will sub that second equation into the first one and solve for h:
h + c = 762 becomes
h + h + 62 = 762 and
2h + 62 = 762 and
2h = 700 so
h = 350. So 350 hamburgers were sold and 762 - 350 is the number of cheeseburgers. 412 to be exact.
