Questions & Step-by-Step Solutions
A store increases the price of a product by 25% and then offers a discount of 10%. If the original price was $200, what is the final price?
Correct Answer: 225
Steps
Concepts
Step 1: Start with the original price of the product, which is $200.
Step 2: Calculate 25% of the original price. 25% of $200 is $50 (because 25/100 * 200 = 50).
Step 3: Add the increase to the original price. $200 + $50 = $250. This is the new price after the increase.
Step 4: Calculate 10% of the new price. 10% of $250 is $25 (because 10/100 * 250 = 25).
Step 5: Subtract the discount from the new price. $250 - $25 = $225. This is the final price.
