(10/100) x 100 = 10%
Discount = 10% of $100 = $10
Price after discount = $100 – $10 = $90
Example 2: A bank offers a 5% interest rate on savings accounts. If you deposit $1000, how much will you earn in interest after one year?
(5/100) x 1000 = 5%
Interest = 5% of $1000 = $50 (See Also: Find Two Consecutive Even Integers Whose Sum Is 126? Solution)
Example 3: A company has a market share of 20% in the industry. If the industry is worth $100 million, how much is the company’s market share worth?
(20/100) x 100 = 20%
Market share value = 20% of $100 million = $20 million
