Answer:
The revenue will be maximum when the price of each umbrella will be $12.
Step-by-step explanation:
Let the number of umbrellas sold n(c) is a linear function of the cost of each umbrella (c, say).
And the relation is n(c) = xc + y ......... (1)
Now, at c = 9 dollars, n(9) = 22500 and at c = 16 dollars, n(16) = 12000
Hence, from the equation (1) we get
22500 = 9x + y ........ (2) and
12000 = 16x + y .......... (3)
Hence, from equations (2) and (3) we get (16x - 9x) = -10500
⇒ 7x = -10500
⇒ x = -1500
Now, from equation (2), we get 22500 = 9 × (-1500) + y
⇒ y = 36000
Therefore, the relation is n(c) = - 1500c + 36000
Now, the revenue will be given by R = n(c) × c = - 1500c² + 36000c
Condition for maximum revenue is
⇒ c = 12 dollars.
Therefore, the revenue will be maximum when the price of each umbrella will be $12. (Answer)
