Real-World Percentage Power

Sarah walks into a shop and sees a £80 jacket with "25% OFF!" splashed across it. At the till, she's told there's an additional 5% student discount. Meanwhile, her brother Jake just got a 12% pay rise on his £28,000 salary, but he's worried about the 20% VAT on his new gaming laptop. From shopping discounts to salary negotiations, from tax calculations to investment returns - percentages are everywhere in real life, and mastering them gives you the power to make smart financial decisions.

Exam Success Tips

  • Always show working: Even if you use a calculator, show the calculation setup
  • Check answers make sense: A 90% discount shouldn't give you more than the original price!
  • Read carefully: Is the percentage being added or subtracted? Is VAT included or excluded?
  • Use multipliers for efficiency: 1.15 for 15% increase, 0.75 for 25% decrease
  • Round appropriately: Money usually rounds to pence, percentages to 1 decimal place
