Answer:
275
Step-by-step explanation:
t = total sold
c = cheeseburgers h = hamburgers
c + h = t total is equal to cheeseburgers + hamburgers
we know that
c + h = 481
and that c = h - 69
so we can rewrite the first equation as
(h-69) + h = 481
2h = 481 + 69
2h = 550 h=550/2=275
so there 275 hamburgers were sold
