    Answer:

    3.5 hours

    Step-by-step explanation:

    use this linear equation

    y = 45x + 55     y is the amount earned and x is the hours worked

    plug in 212.50 for y then solve for x

    212.50 = 45x + 55

    157.5 = 45x

    3.5 = x

    so he worked for 3.5 hours or 3 hours and 30 minutes

    hope this helps <3
