Scenario: You are shopping for a new pair of shoes that cost $80. There is a 20% discount on the shoes. How much money will you save with the discount?
Answer: To calculate the discount amount, you can use the formula:
Discount amount = Original price x Discount rate
Discount amount = $80 x 0.20 = $16
Explanation: By applying a 20% discount, you will save $16 on the shoes.
Question 2:
Scenario: A store is offering a 15% discount on all electronic gadgets. If a laptop originally costs $1200, what will be the discounted price of the laptop after the 15% discount?
Answer: To find the discounted price, you can use the formula:
Discounted price = Original price - Discount amount
Discount amount = Original price x Discount rate
Discount amount = $1200 x 0.15 = $180
Discounted price = $1200 - $180 = $1020
Explanation: After applying a 15% discount, the laptop will cost $1020.

Scenario: During a sale, a clothing store offers a 25% discount on all items. If a dress is priced at $60 before the discount, what is the final price of the dress after the discount?
Answer: Using the formula:
Discounted price = Original price - Discount amount
Discount amount = Original price x Discount rate
Discount amount = $60 x 0.25 = $15
Discounted price = $60 - $15 = $45
Explanation: After the 25% discount, the dress will be priced at $45.
