    If you would like to know how much does Claire pay for the dress, you can calculate this using the following steps:

    on sale for 30% off:

    30% of $160 = 30% * 160 = 30/100 * 160 = $48

    $160 - $48 = $112

    an additional 10% off:

    10% of $112 = 10% * 112 = 10/100 * 112 = $11.2

    $112 - $11.2 = $100.8

    the sales tax ... 7.5%

    7.5% of $100.8 = 7.5% * 100.8 = 7.5/100 * 100.8 = $7.56

    $100.8 + $7.56 = $108.36

    The correct result would be c. $108.36.
