    Answer:

    360th customer

    Step-by-step explanation:

    To find the customer that will receive both the free popcorn and the free movie rental, we have to list the multiples of 40 and 45 until we get a multiple that is the same for both of them.

    Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440

    Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360

    360 is the first multiple that is same for multiples of 40 and 45

    So the 360th customer will receive both items.

    (Sorry if my explanation is hard to understand. I haven’t done this kind of math in a while)

    Hope it helps (●’◡’●)
