Each participant on the school trip has to pay € 7 for the booked bus. Three students fell ill and did not go on a trip. Everyone then had to pay € 8 for the bus. How many students took part in the trip?

Correct answer:

n =  21

Step-by-step explanation:


7·(n+3) = 8n

7·(n+3) = 8·n

n = 21


n = 21/1 = 21

n = 21
