To determine the total cost for a class of 25 students to see The Nutcracker at the Boston Ballet, we can set up an equation using two variables.
Let:
- \( C \) = total cost
- \( n \) = number of students (in this case, 25)
The cost equation can be expressed as follows:
\[ C = 50 + 15n \]
Here, \( 50 \) is the flat rate charged by the Boston Ballet, and \( 15n \) represents the cost of the tickets for \( n \) students at $15 per ticket.
Now, substituting \( n = 25 \) into the equation:
\[ C = 50 + 15(25) \]
Calculating the ticket cost:
\[ C = 50 + 375 \]
Now adding the flat rate:
\[ C = 425 \]
Thus, the total cost for a class of 25 students to see The Nutcracker would be $425.00.
