Conor is going to the movie theater. A ticket to a movie costs "t" dollars, and there is a 15% amusement tax on each ticket.

To calculate the total cost of Conor's movie ticket including the amusement tax, we can write two expressions in terms of "t."

1. Expression for the amusement tax: The amusement tax is 15% of the ticket price \( t \). Therefore, the tax amount can be expressed as: \[ 0.15t \]

2. Expression for the total cost: The total cost of the ticket including the tax can be expressed as the sum of the ticket price and the tax amount: \[ t + 0.15t \]

Alternatively, we can also express the total cost as a single expression using the factor of \( t \): \[ 1.15t \]

So, the two expressions in terms of "t" showing Conor's total cost are:

1. \( t + 0.15t \)
2. \( 1.15t \)
