Final answer:
The profit y in terms of the number of tickets sold x for the drama club is represented by the equation y = 3x - 24, considering the $24 cost for supplies and $3 income per ticket.
Step-by-step explanation:
To determine the profit y the drama club makes in terms of the number of tickets sold x, we need to take into account the cost of supplies and the income from ticket sales. The drama club spends $24 on supplies for a one-act play. Since they sell tickets for $3 each, the profit equation will be y = 3x - 24. This equation shows that for each ticket sold, the club earns $3, and the $24 for supplies is a one-time cost that is subtracted from the total revenue to calculate profit.
