In 3 years, a gym's membership went up from 6400 to 8400. Which expression shows how to find the percent increase?

Respuesta :

[tex]Change=100* \frac{8400}{6400} [/tex]

[tex] \frac{8400}{6400} =1.31[/tex]

[tex]1.31*100=131[/tex]

The total increase is [tex]131%[/tex].

For the percent growth rate:

[tex]growth= \frac{131}{3} [/tex]

Solve for the percent growth rate :)
