Math Problem Statement
Please Answer these questions:
- A company sells its product for $46 per unit. Write an expression for the amount of money received (revenue R) from the sale of x units of the product.
R =
2. Suppose a calculator manufacturer has the total cost function
C(x) = 20x + 6200
and the total revenue function
R(x) = 66x.
(a) What is the equation of the profit function P(x) for the calculator? P(x) =
(b) What is the profit on 2400 units? P(2400) = $
- Suppose a ceiling fan manufacturer has the total cost function
C(x) = 35x + 1320
and the total revenue function
R(x) = 68x.
(a) What is the equation of the profit function P(x) for this commodity?
P(x) =
(b) What is the profit on 20 units?
P(20) =
Interpret your result.
The total costs are less than the revenue.The total costs are more than the revenue. The total costs are exactly the same as the revenue.
(c) How many fans must be sold to avoid losing money? fans
- Suppose a computer manufacturer has the total cost function
C(x) = 72x + 3600
(in dollars) and the total revenue function
R(x) = 372x
(in dollars).
(a) What is the equation of the profit function P(x) (in dollars) for this commodity? P(x) =
(b) What is the profit (in dollars) on 348 items? P(348) = $
