how did you get that answer
Answered by Ms. Sue
It looks as though Ariana is wrong.

0.2x = 38

x = 38 / 0.2

x = 190 members
Answered by Rebecca
why would u multiply .2 instead of .8
Answered by Ms. Sue
I divided by 0.2 because that's the percent that signed up. We only know how many that did sign up. 80% did not sign up.

20% of the members is 38. We need to know what 20% of an unknown number equals 38.
