Step-by-step explanation:
Answer:
33.49 cubic units
Step-by-step explanation:
The demand function is
... q(p) = 640 + 40(8.00-p)/0.10 . . . a drop in price of 0.10 sells 40 more sandwiches
... q(p) = 3840 -400p . . . . . . . . . expanded form
... q(p) = 400(9.60 - p) . . . . . . . . factored form
The revenue is the product of price and the quantity sold.
... R(p) = p·q(p)
... R(p) = 400p(9.60 - p)
This is the equation of a quadratic function with zeros at p=0 and p=9.60. Since the zeros of a parabola are symmetric about its vertex, the vertex (maximum) will be halfway between those values, at p=4.80.
The deli should charge $4.80 for a sandwich to maximize revenue.
The answer is A) x+4+2/x-2
