Before going to the register:
Scarf price = $12.50
Nail polish price = $3
At the register:
Since the scarf price is 5% off so the selling price of the scarf is:
= $
= $
= $
= $ 11.875
Hence:
Selling price of scarf is $11.875
The subtotal (scarf and nail polish before tax ) is $(11.875+3) or $14.875
Now:
If 9% tax is applied on the subtotal then the total price including tax will be:
= $
= $
= $ 16.21375
Hence:
The subtotal after applying tax is approximately $16.21
