Final answer:
The mom spent a total of $287.88 on three Taylor Swift concert tickets after applying a 20% discount, with each ticket costing $95.96 following the discount.
Step-by-step explanation:
The question involves calculating the total cost of tickets after a discount is applied. To find out how much the student's mom spent on all three tickets to the Taylor Swift concert with the discount, we first need to calculate the discounted price of a single ticket and then multiply that by the number of tickets.
Original price per ticket: $119.95

Finally, we calculate the total cost for all three tickets:
