Answer:
(a)
(b)
(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

(b)Marginal revenue function R'(x)
If 
Then, the marginal revenue function

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

From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.
Answer:
Approximately what will be saved will be 8.00
Step-by-step explanation:
Here, we want to know the amount that the customer will save
Firstly, we need to know the amount that all will cost
Mathematically, that will be;
24 + 16.12 + 10.5 = 50.62
The amount to be discounted is 15% of this
That will be 15% of 50.62
= 15/100 * 50.62
= 7.593
