Answer:
To find the final sale price of the jacket after a 10% discount, you need to calculate 10% of Php550 and subtract that amount from the original price:
Original price of the jacket = Php550
Discount rate = 10%
Amount of discount = 10% of Php550
\[ \text{Discount} = 0.10 \times 550 = Php55 \]
Final sale price = Original price - Discount
\[ \text{Final sale price} = 550 - 55 = Php495 \]
So, after applying a 10% discount, the final sale price of the jacket is Php495.
