Answer:
I'm just going to assume inbetween 4 and 2 is a multiplication symbol. If it isn't, just comment under and I'll tell u the answer.
hope this is right :D
(X-2)(x^2-6x+2) so yes, (x-2) is in there
Answer:
A i'm pretty sure
Step-by-step explanation:
Answer:
<em>The rebate should be $220</em>
Step-by-step explanation:
<u>Demand Curve</u>
It's the relationship between price (P) and quantity (Q) demanded a certain product or service.
(a) We need to find the function that relates both magnitudes assuming a linear equation. The equation of a line can be found with the point-point formula:

Two sets of data are given: 100 Blu-ray disc players are sold a week at $600 each. The ordered pair for this condition is (P,Q)=(600,100).
The other point comes from the market survey: The number of units sold will increase by 80 (100+80=180) when the price goes down $40 (600-40=560). The new point is (P,Q)=(560,180)
We set up the equation of the demand

Rearranging

Or

Simplifying

(b) The revenue function is Q times the price

Solving the equation of the demand for P

Thus, the revenue is


(c) To find the optimum value of the revenue, we take the derivative of R and equate to 0

Solving
Q=560 units a week
For which the revenue is


And the price is


The rebate should be $600-$280=$220
