Question

A class trip cost a total of $414, including a museum ticket and lunch for each student. Three students were sick on the day of the trip and did not attend, so the total cost dropped to $360. How many students went on the trip?

I WILL GIVE BRAINLIEST FOR EXPLAINATION!!!!!!!!

Answer 1

• Let total students be x
• Students didn't came to lunch be y

ATQ

• x+y=414---(1)
• x-y=360--(2)

Substracting both

$\\ \sf\longmapsto 2y=54$

$\\ \sf\longmapsto y=27$

• 3 students paid 27

each paid

$\\ \sf\longmapsto \dfrac{27}{3}=9$

Now

Total students went on trip

$\\ \sf\longmapsto \dfrac{360}{9}$

$\\ \sf\longmapsto 40$
