No, you didn't take into consideration the brackets.

Profit/Loss = (3x) - (30 + 2.5x) = 3x - 30 - 2.5x

Then you simplify.

5.5x = 30
x = 5.45?

Unknown008 · Mar 13, 2011, 06:03 AM

Um.. no.

Profit/Loss = 3x - 2.5x - 30

What is 3x - 2.5x ?

henrypoo · Mar 13, 2011, 06:05 AM

0.5x - 30?
x=60?

Yes, profit/loss = 0.5x - 30

That's it. There is nothing to solve.

What you just got, is the number of kg that the distributor needs to sell to get neither profit nor loss. :)

so the final answer for cost function is C(x) = 30+2.5x and revenue function is 0.5x - 30?

Would you mind reply a little bit faster? Sorry to impose you. But I need to hand in tomorrow

The revenue is simply 3x, as I told you in post #19.

The NET revenue is 0.5x - 30.
