Answer:
The admission fee was $8
Explanation:
1. Each student paid f + 6 dollars (the museum’s admission fee and $6 for lunch)
2. The entire class paid 24*(f + 6) dollars (24 students visited the museum)
3. 24*(f + 6) = 336 ( The class spent a total of $336.)
4. 24f + 144 = 336
5. 24f = 336 - 144
f = 192/24
f = 8
