Question

Write a system of two equations with the variables m and f in each to represent the following problem: To skate at Roller Heaven, each person must pay a monthly membership fee (m) and a fee for each session (f). In January, Art attended 5 sessions and paid $25 in all. In July, he attended 10 sessions, and he paid $40 in all.

Answer 1

No. 2

5f + m = 25 ---------------- 1st equation
10f + m = 40 ---------------- 2nd equation

now use elimination method (or substitution method) to solve the simultaneous equations...

so,,, using elimination,,
5f = 15,
f = 3
therefore, m =10
