Final answer:
The refunded US Ticket Tax from the fare calculation can be determined by multiplying the fare for each leg of the journey by 4 and then calculating 7.5% of the total fare.
Explanation:
The refunded US Ticket Tax from the fare calculation can be determined by examining the fare breakdown. From the given information, it can be observed that the student traveled on the following routes: BWI to ATL, ATL to FLL, FLL to ATL, and ATL to BWI. The fare for each leg of the journey is $43.83. The US Ticket Tax is a percentage of the fare and is usually 7.5%. Therefore, the refunded US Ticket Tax would be 7.5% of the total fare, which is $43.83 * 4 = $175.32. 7.5% of $175.32 is $13.15.
