Answer:

(a) $R(x)=-0.02x^2+610x$

(b) $R'(x)=-0.04x+610$

(c)R'(5400)=$394

Step-by-step explanation:

Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:

p = −0.02x + 610 (0 ≤ x ≤ 20,000)

(a)Revenue function R.

Revenue = Price X Quantity Demanded

Therefore:

R(x)=xp

$=x(-0.02x + 610)\\R(x)=-0.02x^2+610x$

(b)Marginal revenue function R'(x)

If $R(x)=-0.02x^2+610x$

Then, the marginal revenue function

$R'(x)=-0.04x+610$

(c)We want to compute R'(5,400)

$R'(5400)=-0.04(5400)+610\\R'(5400)=394$

From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.
