You first want to figure out the populations for each. Tallahessee has 483,493. New York has 345,876 more than Tallahessee, so you want to add the 2 populations. 483, 493 + 325,876 =809,369. So therefore, New York has 809,369 people. Phoenix has 279,426 less than New York, so you what to subtract the two numbers. 809,369-279,426=529,943. So Phoenix has 529,943. Then, you want to add each number together, which makes 1,822,805.
