Each hour,
x makes b/6 bearings
y makes b/4 bearings
z makes b/3 bearings
Together, each hour, x, y and z together make
b/6+b/4+b/3=b(1/6+1/4+1/3)=b(2/12+3/12+4/12)=b(3/4)=3b/4 bearings.
Time to make b bearings =
b/(3b/4)=4/3 hours = 1 hour 20 minutes.
Answer: A) 30 cards
<u>Step-by-step explanation:</u>

F(x) = (x - 4) (x^2 + 4) would be your answer.
The initial value is 3. The common ratio is -9/3 = -3. The general formula is
.. an = a1*r^(n-1)
So, for your values, ...
.. an = 3*(-3)^(n -1)
