Answer:

1.) $640 2.) 7 years.

Step-by-step explanation:

1000 x .2 = 200      1 yr

1000 - 200 = 800

800 x .2 = 160         2 yrs

800 - 160 = 640

640 x .2 = 128         3 yrs

640 - 128 = 512

ANYWAYS THIS WOULD TAKE TO LONG! SO HERE IS THE ANSWER TO B.

George believes the Art Club students at his school have an unfair advantage in being assigned to the art class they request. He
Whitepunk [10]

Answer:

  class assignment seems to discriminate against Art Club members

Step-by-step explanation:

The probability of getting the requested assignment given that the student was in Art Club was ...

  P(got class | art club) = P(got class & art club)/P(art club)

  P(got class | art club) = (100/500)/(165/500) ≈ 60.6%

__

  P(got class | not club) = P(got class & not club)/P(not club)

  P(got class | not club) = (265/500)/(335/500) ≈ 79.1%

It looks like George's theory may be incorrect, as a significantly greater percentage of non-club students got their requested class than did club students. The class assignment process and art club membership are not independent, suggesting an unfair disadvantage for club students.
