    Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.

    Step-by-step explanation:

    1. Let's review the information provided to us to answer the question correctly:

    Total of orders server at the school cafeteria by Kaitlin, Tony and Juan = 71

    Tony served 9 orders fewer than Kaitlin

    Juan served 2 times as many orders as Kaitlin

    2. How many orders did each one serve?

    For answering this question, we should prepare and write down our equation this way:

    x = Number of orders served by Kaitlin

    2x = Number of order served by Juan (2 times as many orders as Kaitlin)

    x - 9 = Number of order served by Tony (9 orders fewer than Kaitlin)

    x + 2x + x - 9 = 71

    4x = 71 + 9

    4x = 80

    x = 80/4 = 20

    x = 20 ⇒ 2x = 40 ⇒ x - 9 = 11

    Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.
