    Step-by-step explanation:

    Original price is $450

    ⇒$450→100%

    and there is a sale of 6%

    ⇒X→94%

    ⇒the dress cost after 6% sale = X = (450*94) : 100=$423

    But, Alia has 10% discount also

    ⇒$423→94%

    Y→84%

    ⇒The final dress cost = Y = (423*84) : 94=$378

    if you mean 6% is added to the dress as a tax:

    Original price is $450

    ⇒$450→100%

    ⇒X→106%

    ⇒the dress cost after 6% tax = X = (450*106) : 100=$477

    But, Alia has 10% discount also

    ⇒$477→100%

    Y→90%

    ⇒The final dress cost = Y = (423*90) : 100=$429.3
