The adult population of a town in 2000 was 400. The child population of the town in 2000 was 120. Both the adult and child populations increased by the same percent from 2000 to 2010. If the adult population in 2000 was 500, how many children lived in the town then?

Respuesta :

Answer:

150

Step-by-step explanation:

500 is 125% of 400 (500/400) so you need to get what 125% of 120 is

120                              x   1.25                            =150

^number of children        ^125% as a decimal
