Question

In 1950, 35.1 million people lived in suburban areas. By 1990, that number had increased to 120 million people. What was the percent increase in subur- ban population?

Answer 1

Answer:

241.88%

Step-by-step explanation:

Given that :

Initial suburban population in 1950 = 35.1 million

Suburban population in 1990 = 120 million

Percentage increase in suburban population :

[(population in 1990 - population in 1950) / population in 1950] * 100%

[(120,000,000 - 35,100,000) / 35,100,000] * 100%

[(84,900,000) / 35,100,000] * 100%

2.4188034 * 100%

241.88034%

= 241.88%

Hence, the percentage increase in suburban population is 241.88%
