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

The percent increase in suburban population from 1950 to 1990 is approximately 242.67%.

Step-by-step explanation:

To find the percent increase in suburban population from 1950 to 1990, we need to calculate the difference between the two numbers and then divide it by the original number.

The difference is 120 million - 35.1 million = 84.9 million.

The percent increase is (84.9 million / 35.1 million) x 100% = 242.67% (rounded to two decimal places).

Therefore, the percent increase in suburban population from 1950 to 1990 is approximately 242.67%.

Answer 2

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%
