There are 81 libraries in Chicago for a population of 2.67 million. If Houston has a population of 2.533 million with only 138 Starbucks and Atlanta has just 498,000 people, how many Starbucks would Atlanta expect to have if it was proportional to Brooklyn in terms of Starbucks to population?

Round your answer to the nearest whole number.

Using the ratio of Starbucks to population from Houston, it's calculated that if Atlanta were proportional, it would have approximately 27 Starbucks locations.

Explanation:

To calculate how many Starbucks Atlanta would have if it was proportional to Brooklyn, we must first understand the given ratio of Starbucks to the population in Houston. Houston has 138 Starbucks for a population of 2.533 million. This gives us a ratio of 138 Starbucks per 2.533 million people, or approximately one Starbucks for every 18,362 people (2,533,000 / 138 ≈ 18,362).

Applying this ratio to Atlanta's population of 498,000 people:

Divide Atlanta's population by the Starbucks-to-population ratio we found for Houston to get the expected number of Starbucks in Atlanta: 498,000 / 18,362 ≈ 27.1.
Round the result to the nearest whole number to find that Atlanta would have approximately 27 Starbucks.

Therefore, if Atlanta's number of Starbucks was proportional to Houston's, one would expect Atlanta to have around 27 Starbucks locations.
