Final answer:
The equation that could be used to determine the cost per ticket for the drama club is 125 + 120t = 180 + 110t.
Step-by-step explanation:
To determine the cost per ticket, let's assign t as the cost per ticket. According to the given information, on Friday night, the drama club collected $125 in donations and sold 120 tickets, and on Saturday night, they collected $180 in donations and sold 110 tickets. Since the drama club had the same amount of money at the end of each night, we can set up the equation:
Donations on Friday night + (Cost per ticket * Number of tickets sold on Friday night) = Donations on Saturday night + (Cost per ticket * Number of tickets sold on Saturday night)
$125 + 120t = $180 + 110t
Therefore, the equation that could be used to determine t, the cost per ticket, is 125 + 120t = 180 + 110t.
