Discount: A Percent of Decrease

The video tutorial explains how to calculate the final price of a sweater after applying multiple discounts. It begins by detailing the original price and the discounts available: a 10% sale discount and a 25% coupon discount. The tutorial then evaluates a customer's claim that a single 35% discount on the original price would yield the same result. Through step-by-step calculations, it demonstrates that the customer's method is incorrect, as the discounts apply sequentially, not cumulatively. The final price is determined to be $27, not the $26 suggested by the customer's method.

What is the original price of the sweater before any discounts?

• $30

• $35

• $40

• $45

After applying a 10% discount to the original price, what is the new price of the sweater?

• $32

• $34

• $30

• $36

How much is the 25% coupon worth when applied to the sale price of $36?

• $8

• $9

• $10

• $11

What is the final price of the sweater after both discounts are applied?

• $25

• $26

• $27

• $28

Why is the customer's claim of taking 35% off the original price incorrect?

• Because 35% of the original price is more than the combined discounts.

• Because 35% of the original price is equal to the combined discounts.

• Because 35% of the original price is not a valid discount.

• Because 35% of the original price is less than the combined discounts.
