the third option

sorry if the answer is wrong
Answer:
1/2. (0.5)
My apologies for no explanation, I just put it in my calculator.
Check attached image for work; your answer is x = 95.
$20+5.75b
Flat fee of $20 plus
5.75 for <em>each</em> bucket of balls
The variable <em>b</em> represents each bucket that you use
To simplify this expression you would factor out the greatest common factor which is y^2.
9y^2 - 11xy^2 -----> Factor out y^2
y^2(9 - 11x) ----> This should be as far as you can go, meaning this is your final answer!
Hope this helps!
