Manny’s Music Rental charges a fee of $40 plus $25 per month to rent a saxophone. Sid’s Saxophones charges $25 plus $30 per month to rent the same saxophone.

Write a system of linear equations to represent this situation.

• y = 40x + 25

  y = 30x + 25

• y = 25x + 40

  y = 30x + 25

• y = 25x + 40

• y = 25x + 40

  y = 25x + 30
