Answer:
1. Calculate the discount amount by multiplying the normal price (₱650.00) by the discount percentage (20% or 0.20): Discount amount = ₱650.00 * 0.20 = ₱130.00 2. Subtract the discount amount from the normal price to find the final price that Tina will pay: Final price = ₱650.00 - ₱130.00 = ₱520.00 Therefore, Tina will pay ₱520.00 for the shoes after the 20% discount.
