Question

In 2000 the city of Las Vegas had a population of 478,434. In 2007 there were 558,880 people living in Las Vegas. How many more people were living in Las Vegas in 2007 than in 2000?

Answer 1

80,446

You would subtract the 2000 population from the 2007 population.

558,880-478,434= 80,446

Answer 2

2000 = 478'434
2007 = 558'880
so
558'880 - 478'434 = 80446

80446 more people live in las vegas in 2007 than back in 2000
hope this helps
