Ex 7.2, 3 The population of a city decreased from 25,000 to 24,500. Find the percentage decrease. Initial population = 25,000 Final population = 24,500 Decrease in population = Initial population β Final population = 25,000 β 24, 500 = 500 Percentage decrease in population = (π·ππππππ π ππ ππππ’πππ‘πππ)/(πΌπππ‘πππ ππππ’πππ‘πππ) Γ 100% = πππ/(ππ,πππ) Γ 100% = 5/250 Γ 100% = 5/25 Γ 10% = 1/5 Γ 10% = 2%
