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]
