    Common Percentage Calculations<\/h2>\n

    What is X% of Y?<\/strong> Example: What is 20% of 150? Answer: 150 \u00d7 0.20 = 30.<\/p>\n

    Percentage increase:<\/strong> Example: Price went from 80 to 100. Increase = (100-80) \u00f7 80 \u00d7 100 = 25%.<\/p>\n

    Percentage decrease:<\/strong> Example: Price dropped from 100 to 75. Decrease = (100-75) \u00f7 100 \u00d7 100 = 25%.<\/p>\n

    Retail shoppers calculate discounts \u2014 a 30% off sale on a $85 item saves $25.50. Students calculate their grade as a percentage of total marks. Investors track portfolio growth as percentage returns. Business owners calculate profit margins and markup percentages. Waiters and diners calculate tips as a percentage of the bill.<\/p>\n

    Percentage vs Percentage Points<\/h2>\n

    These two terms are often confused. If an interest rate rises from 5% to 8%, it increased by 3 percentage points but by 60% (relative increase).
