F(x)=3x+5 over x , what is f(a+2)
Fed [463]

<u>Answer</u>

F(a+2) = (3a+11)/(a+2)


<u>Explanation</u>

F(x) = (3x + 5)/x


If you are to find F(a+2), you replace x with (a+2)


F(a+2) = (3(a+2)+5))/(a+2)

= (3a+6+5)/(a+2)

=(3a+11)/(a+2)

I'm so confused. This question seems contradicting, and need an explanation.
Lerok [7]

Answer:

1/2 or 0.5 dollars per kg of apples

The first thing to do is to find out how much a kg of apples sells for, since the question is only asking for the selling amount of a single kg. Nothing else. Each trip gets 300 dollars and delivers fifty packs. So each Pack, or P = 300/50, or P = 6 dollars

And each pack contains 12 kg of apples, so if P = 6 dollars and P = 12 kg of apples, then 6 dollars = 12 kg of apples

then 1 kg apples = 6/12, or 1/2.

So a single Kg of apples cost 0.5 dollars
