Answer:

To find the discount rate, you can use the formula:

Discount Rate = (Discount Amount / Original Price) x 100

In this case, the discount amount is ₱50 and the original price is ₱500.

Plugging in these values into the formula:

Discount Rate = (50 / 500) x 100 = 0.1 x 100 = 10 %

So the discount rate is 10%. That means the watch was sold at 10% off of its original price.
