5. Practical Examples

Here are a few examples to help you understand better:

• Example 1: Price Increase
  Original price: $40
  New price: $50
  Calculation:

50−4040×100=1040×100=0.25×100=25%\frac{50 – 40}{40} \times 100 = \frac{10}{40} \times 100 = 0.25 \times 100 = 25\%4050−40​×100=4010​×100=0.25×100=25%

So, the price increased by 25%.

• Example 2: Salary Raise
  Original salary: $2000
  New salary: $2200
  Calculation:

2200−20002000×100=2002000×100=0.1×100=10%\frac{2200 – 2000}{2000} \times 100 = \frac{200}{2000} \times 100 = 0.1 \times 100 = 10\%20002200−2000​×100=2000200​×100=0.1×100=10%

Your salary increased by 10%.

• Example 3: Increase in Subscribers
  Original subscribers: 1000
  New subscribers: 1500
  Calculation:

1500−10001000×100=5001000×100=0.5×100=50%\frac{1500 – 1000}{1000} \times 100 = \frac{500}{1000} \times 100 = 0.5 \times 100 = 50\%10001500−1000​×100=1000500​×100=0.5×100=50%
