Answer:
Original price =$ 92.5
Step-by-step explanation:
Let the original price of the dress be $x.
Since 10% discount is given on all items during sale in the departmental store.
Therefore,
Original price - 10% discount of original price = $ 83.25
[tex]\therefore x - \frac{10}{100} x= 83.25\\\therefore x - 0.1x =83.25\\\therefore 0.9x = 83.25\\\therefore x = \frac{83.25}{0.9} \\\therefore x = \$92.5[/tex]
