Question 695332: Amanda pays an annual fee of $100 to belong to a gym, plus a monthly fee of $10. Maria pays only a monthly fee of $20
I found the answer to part a which was: write a system of equations to represent this situation. My answer was: y=10x+100 and y=20x.
I need you to check that and find part b: Solve the system by graphing. Explain what the solution means.
I will need an answer tonight which is 12/17
