Each student pays 7.25 for lunch.
Multiply that by 25 for the total lunch cost: 25 * 7.25 = 181.25.
Subtract the lunch total from the total cost to find the total ticket amount:
443.75 - 181.25 = 262.50
Now divide total ticket amount by 25 students to find the cost of one ticket:
262.50 / 25 = $10.50
The first choice is the correct answer.
