So the first thing you need to do is figure out how much you'll be paying in the first place. Then you can subtract that from 100 to get your change.
Step 1: Find out the costs of the tickets
2 side tickets = 2 (10.25) = 20.5
3 center tickets = 3 (12.5) = 37.5
2 balcony tickets = 2 (14.75) = 29.5
Note: get the prices from the table and multiply them by how many of tickets are being bought
Step 2: Add to find the total cost of the tickets
20.5 + 37.5 + 29.5 = 87.5
Note: get the numbers to add from the answers to step 1
Step 3: To find out how much change you got, subtract the total cost from 100
100 - 87.5 = 12.5
Note: you paid with 100 dollars, bought 87.5 dollars worth of tickets, so you have 12.5 dollars left over
To finish off, just write 12.5 as $12.50! Your answer is B
