    91.2 ounces

    Step-by-step explanation:

    Let's make a proportion using this setup:

    ounces/boxes=ounces/boxes

    There are 57 ounces in 5 boxes, and x ounces in 8 boxes.

    57 ounces/5 boxes = x ounces/8 boxes

    57/5=x/8

    Now we have to solve for x. x and 8 are being divided. To undo this, multiply both sides by 8, because multiplication is the opposite of division.

    8*57/5=x/8*8

    The 8s on the right will cancel, so we are left with:

    8*57/5=x

    8*11.4=x

    91.2=x

    There are 91.2 ounces in 8 boxes
