    So initiation fee is 12.75

    0.75 per video so

    total cost = iniation fee+0.75 times number of videos or

    total cost=12.75+0.75 times v

    0.75 times v=0.75v so

    total cost=12.75+0.75v

    if total cost=105.75 then subsitute

    105.75=12.75+0.75v

    subtract 12.75 from both sides

    93=0.75v

    multiply both sides by 100 to clear decimal

    9300=75v

    divide both sides by 75

    124=v

    she rented 124 videos

    A:total=12.75+0.75v

    B:124 videos
