Question

To skate at Roller Heaven, each person must pay a membership fee (m) and a fee for each session (f). Art attended five sessions and paid $25 in all. Later, when he had attended 10 sessions, he paid $40 in all. How much is the membership fee and how much are the sessions.
Write a system of two equations with the variables m and f in each to represent this problem.

Answer 1

m+5f=25
m+10f=40

Answer 2

m=25-5f
subs in eq 2
25-5f+10f=40
5f=15
f=$3
then
m=25-5(3)
m=10

Answer 3

f=$3
and m=$10
