    78.5 cm² of plastic is needed to make a similar shaped 2.5 ounce bottle.

    Step-by-step explanation:

    It is given that,

    It takes 471 cm² of plastic to make a 15 ounce bottle.

    Let us assume,

    The plastic required to make 2.5 ounce bottle = x cm²

    To find the x value:

    Comparing the given data,

    471 plastic / 15 ounce bottle = x plastic / 2.5 ounce bottle

    Keeping x alone on one side and cross multiplying the denominator,

    (471 / 15) * 2.5 = x

    31.4 * 2.5 = x

    78.5 = x

    Therefore, the value of x = 78.5 cm²

    The plastic required to make 2.5 ounce bottle is 78.5 cm²
