Question

Chicago is home to 2.706 million people and the city sees approximately 55 million visitors each year. China has a population of 1.393 billion. If their visitors were proportional to Chicago, how many visitors could China expect? Write your answer in scientific notation rounded to two decimal places. Provide your answer below: x 10^ visitors

Answer 1

China could expect approximately 2.83 x 10^4 visitors if their visitors were proportional to Chicago.

Step-by-step explanation:

To find out how many visitors China could expect if their visitors were proportional to Chicago, we can set up a proportion based on the ratio of the populations of the two places. The population of Chicago is 2.706 million and it receives 55 million visitors a year. Let's call the number of visitors China could expect 'x'. So, the proportion would be:

2.706 million / 55 million = 1.393 billion / x

Cross multiplying, we get:

2.706 million * x = 55 million * 1.393 billion

Simplifying the right side, we have:

2.706 million * x = 76.615635 billion

Dividing both sides by 2.706 million, we get:

x = 76.615635 billion / 2.706 million

x = 28,331.225

Rounded to two decimal places and written in scientific notation, China could expect approximately 2.83 x 10^4 visitors.
