- New Value = 65,000
Now, apply the formula: Percent Growth=65,000–50,00050,000×100\text{Percent Growth} = \frac{65,000 – 50,000}{50,000} \times 100Percent Growth=50,00065,000–50,000×100 Percent Growth=15,00050,000×100=30%\text{Percent Growth} = \frac{15,000}{50,000} \times 100 = 30\%Percent Growth=50,00015,000×100=30%
