How Does a Number Increase by 20% to Reach 120? A Clear Explanation
Key Insights
To reach 120 after a 20% increase, start with the original number, call it x. A 20% increase means adding 0.20×x to x, resulting in x + 0.20x = 1.20x. Set that equal to 120: 1.20x = 120. Solving for x involves dividing both sides by 1.20: x = 120 ÷ 1.20, which calculates to 100. This straightforward algebra confirms 100 is the starting number—no hidden tricks, just precise mathematics.
This approach applies universally, whether analyzing salary growth, inventory value changes, or key performance indicators in business. Understanding this process builds confidence in interpreting trends and forecasts relevant to modern US experiences.
