During the academic year 2017-2018 the (total annual) in-state cost to attend the University of Texas was $25,440.

Determine the annual cost of tuition in dollars.

It is not specified in the question how much of the $25,440 is allocated towards tuition and how much is allocated towards other expenses such as room and board, books, fees, etc. Therefore, we cannot determine the annual cost of tuition in dollars.

To determine the annual cost of tuition at the University of Texas, we need to subtract the additional expenses from the total annual cost. These additional expenses may include room and board, books, transportation, and other personal expenses.

Assuming that the $25,440 represents the total annual cost, including tuition, and not just the additional expenses, we can conclude that the annual cost of tuition is $25,440.
