    It sold for $9.20 more in 1992 than in 1982.

    It sold for $20.70 in 1992.

    Step-by-step explanation:

    The price in 1982 was $11.50.

    The price increased by 80% of $11.50.

    We need to find 80% of $11.50.

    To find a percent of a number, multiply the percent by the number.

    80% of $11.50 =

    = 80% * $11.50

    = 0.8 * $11.50

    = $9.20

    It sold for $9.20 more in 1992.

    The price in 1992 is the original price of the belt plus the amount of increase.

    $11.50 + $9.20 = $20.70

    It sold for $20.70 in 1992 than in 1982.
