The correct answers are:
D) all of the above; and
C) multiply the original price by 85%
Step-by-step explanation:
When looking for the best deal, it is a good idea to check the prices of items at multiple stores. Some stores carry identical brands and items at different prices.
It is also a good idea to clip coupons. These offer an additional discount.
You should also wait for the item to go on sale, to save extra money.
When calculating a 15% off discount, we are paying 100-15 = 85% of the original price. This means to calculate the amount of the item once it's discounted, we take 85% of the original amount.
