Question

The population of Mathville is 38% more than it wasduring the 2010 census. If the population of Mathvilleis 43,332 people, what was its population in 2010?

Answer 1

Population now = 43,332 (38% more than in 2010)

We have to write an equation:

x (1+38/100) = 43,332

Where x is the population in 2010

Solve for x:

x (1+0.38) = 43,332

1.38x=43,332

x= 43,332/1.38

x= 31,400
