Final answer:
The number of tickets purchased today is 13.
Step-by-step explanation:
To find the number of tickets purchased, we need to add up the totals of all the ticket purchases until we reach or exceed $813.75. Let's go through the list:
- $56.75
- $43.25
- $65.00
- $25.50
- $18.75
- $59.00
- $21.50
- $44.50
- $12.50
- $43.00
- $89.50
- $99.35
- $235.75
If we add up the first 12 totals, we get $647.35. Adding the last total of $235.75 gives us a total of $883.10, which is greater than $813.75. So, the number of tickets purchased today is 13.
