Answer:
Number of students who went on the field trip = N - 6 .
We subtract 6 from the total number of students to get the number of students who went on the field trip.
Step-by-step explanation:
i) let the number of students in the club be = N
ii) If all but 6 students went on the trip then to we can write an expression for the number of students on the field trip by subtracting 6 from N. Therefore we can write the expression as
number of students who went on the field trip = N - 6
