To determine the total cost for a school to take a class of 25 students to see "The Nutcracker," we can define the following variables:
- Let \( x \) represent the number of tickets (which, in this case, would be the same as the number of students).
- Let \( C \) represent the total cost.
Given the pricing structure from the Boston Ballet, we can establish the following equation based on the flat rate and the cost per ticket:
\[ C = 50 + 15x \]
For this problem, since there are 25 students, we substitute \( x = 25 \) into the equation:
\[ C = 50 + 15(25) \]
Now, we can calculate \( C \):
- Calculate \( 15 \times 25 = 375 \)
- Add the flat rate: \( C = 50 + 375 = 425 \)
Therefore, the total cost for the school to take a class of 25 students to see "The Nutcracker" is $425.00.
