    You would expect 13 broken crayon boxes out of 130 boxes.

    Step-by-step explanation:

    It is given that,

    Out of 20 boxes of crayons from the shelf Jerry finds 2 boxes of broken crayon.

    Therefore, for 10 boxes of crayon from the shelf, he could find 1 broken box of crayon.

    10 boxes = 1 broken box

    To find the number of broken boxes out of 130 boxes:

    Divide 130 by 10,

    ⇒ 130 : 10

    ⇒ 13 broken boxes.

    ∴ You would expect 13 broken crayon boxes out of 130 boxes.
