Answer

a. 960,000 trips using public transportation b. 47,040,000 trips not using public transportation

Work Step by Step

a. Percent= 2 ;whole= 48 million. For the sake of simplicity, use 48 now. $\frac{x}{48}=\frac{2}{100}$ Write the fraction in the lowest terms: $\frac{x}{48}=\frac{1}{50}$ Cross products: 50x=48 Solve for x. Multiply x times a million (1,000,000) to get the full answer. $x=.96$ $x=960000$ b. $48,000,000-960,000=47,040,000$
