Denny bought tickets to the circus. He bought 3 child tickets. The child tickets were $5 less than the adult tickets. He spent $45 total. Which equation can be used to find the price of an adult ticket, t?

Let's assume that the price of an adult ticket is t dollars.

Since the child tickets were $5 less than the adult tickets, the price of a child ticket would be t - $5.

Since Denny bought 3 child tickets, he spent a total of 3(t - $5) dollars on child tickets.

He also spent $45 total, so we can set up the equation:

3(t - $5) = $45

This equation can be used to find the price of an adult ticket, t.
