    no, because
    $120-15%=$102
    $102+%6=$108.12

    so %6 represents tax
    and 15% is his discount

    if you were to take away %9 then you would get $109.20
    $120-9%=109.20
    so Dwayne is incorrect, because $108.12 ( his true final price) isn’t equal to $109.20 (the price it would be if it was 9% off)

    I hope this helps!
