Question 7.

Clearwater, Florida, had a population of 107,685 in 2010. Coral Springs had a population of 121,096. Orlando had a population of 238,300. What was the total population of the three communities?

Answer:

Total population of the three communities = 467,081.

Explanation:

Population of Clearwater, Florida in 2010 = 107,685.

Population of Coral Springs in 2010 = 121,096.

Total population of the three communities = Population of Clearwater, Florida in 2010 + Population of Coral Springs in 2010 + Population of Orlando in 2010

= 107,685 + 121,096 + 238,300

= 228,781 + 238,300
