Final answer:
To find the number of tickets sold by Lincoln High School, use the equation 12 × t = 5,100, where t represents the number of tickets sold, and solve for t.
Step-by-step explanation:
To determine how many tickets were sold for a play at Lincoln High School that earned $5,100 in ticket sales with each ticket costing $12, we can represent the number of tickets sold as t and set up an equation. Since the total revenue is the product of the number of tickets sold and the price per ticket, the equation would be:
12 × t = 5,100
This equation can be used to find the value of t, representing the number of tickets sold, by dividing both sides of the equation by 12.
