Answer:
165
Step-by-step explanation:
Let o and b represent the numbers of orchestra and balcony tickets bought, respectively.
o + b ≥ 250 . . . . at least 250 tickets will be bought
o = b - 80 . . . . . there will be 80 fewer orchestra than balcony bought
Substituting for o, we have ...
(b -80) +b ≥ 250
2b ≥ 330 . . . . . . . add 80
b ≥ 165 . . . . . . . . .divide by 2
The least number of balcony tickets the club could buy is 165.
