    Answer: 20 tickets

    Step-by-step explanation:

    From the question, we are informed that Shelby sold 75 raffle tickets for the school fundraiser over a 3-year period while Kelly sold 15 less tickets than Shelby. This means that the number of tickets sold by Kelly is:

    = 75 – 15

    = 60 tickets

    The number of tickets sold by Kelly each year on average will be:

    = Number of tickets sold / Number of years.

    = 60/3.

    = 20 tickets

    over the last 3 years
