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
