Danny bought tickets to the circus. He bought three 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 say the price of an adult ticket is t dollars.
Since the child tickets were $5 less than the adult tickets, the price of each child ticket would be t - $5.
Danny bought three child tickets, so he spent 3 * (t - $5) on child tickets.
The total amount Danny spent on tickets was $45, so we can write the equation:
t + 3 * (t - $5) = $45.
