Question

At a certain concert hall, Orchestra and Balcony tickets were sold for a Friday night concert. The Orchestra and Balcony tickets sold for $30 and $15, respectively. In order to break even with their expenses, the hall must sell at least $4005 worth of tickets.

a) Write a linear inequality that represents the possible combinations of the number of Orchestra and Balcony tickets sold that will meet the concert hall's expenses. Let x be the number of Orchestra tickets sold, and y be the number of Balcony tickets sold. 

Answer 1

I would simply write 30x + 15y ≥ 4005 (or 15y ≥ 4005 − 30x which simplifies to y ≥ 267 − 2x).
