answer: 2144.66 I think. I might be wrong. Please let me know if I'm wrong.
Answer:
![\frac{67}{292} = 0.229](https://tex.z-dn.net/?f=%5Cfrac%7B67%7D%7B292%7D%20%3D%200.229)
Step-by-step explanation:
Out of 292 drawn Americans over 21, 225 of them don't smoke. That means the rest of them are smokers:
So there are 292 - 225 = 67 smokers here.
We can then calculate the portion of Americans over 21 who smoke:
![\frac{67}{292} = 0.229](https://tex.z-dn.net/?f=%5Cfrac%7B67%7D%7B292%7D%20%3D%200.229)
Y = 7x + 4
-4 from both sides
y - 4 = 7x
/ 7 on both sides
(y-4)/7 = x
Answer:
x = (y-4)/7
