Answer: $2.60 in change
Step-by-step explanation: This is how you can calculate it:
Total cost of a pair of tickets = $34.80
Cost of one ticket = $34.80 / 2 = $17.40
You paid with two ten-dollar bills, so that's a total of 2 * $10 = $20
Change received = Amount paid - Cost of ticket
Change received = $20 - $17.40 = $2.60
Accordingly, you should be able to receive $2.60 in change after buying one ticket with two ten-dollar bills.
Hope this helps.
