Question

A firm produces two products A and B. The total cost function of producing “x” items of product A and “y” items of product B is TC = 2x2 + y2 – xy – 49x + 425. Find the number of each type that should be produced to minimize the total cost if the firm is committed the producing 21 items in total.

Answer #1

Given,

And x + y = 21

=> y = 21 - x

TC will be minimum when MC = 0

The firm should produce 14 units of product A and 7 units of product B.

Minimum TC =

X = 14 units and Y = 7 units.

A company determines its total revenue and total cost functions
for producing and selling x items are given by
R(x)=600x−2x2, andC(x)=200+10x.
If the company produces and sells 2 additional items every day
(in other words, dxdt=2), what is the rate of change of profit with
respect to time when they've produced and sold 10 items?

1. A manufacturer produces its products at two locations. Let x
and y be the number of units produced at these two locations. The
cost function is modeled
by
.
C(x,y)=0.25x^2-25x+0.05y^2-12y+3000
Find the number of units that should be produced at each location
to minimize the cost.
2. Given a surface f(x,y)=x^2+y^2-xy and a point (2,1,3) on the
surface, find the slopes of the surface at the point in the
x-direction and the y-direction.

8. Economies of Scope
Definition:
Economies of scope exist when the total cost of producing two
products within the same firm TC(Q1, Q2) is lower than
when the products are produced by separate firms TC(Q1, 0) +
TC(0, Q2). That is, when TC(Q1, 0) + TC(0, Q2) > TC(Q1,
Q2)
A firm’s total cost function is TCQ1,
Q2=100-14Q1Q2+Q12+(Q2)2
where Q1 and Q2 represent the number of units of
goods 1 and 2, respectively.
A. If the firm produces 10 units...

7. Suppose the cost, in dollars, of producing x items is given
by the function C(x) = 1/6x3+ 2x2+ 30.
Current production is at x = 9 units.
(a) (3 points) Use marginal analysis to find the marginal cost
of producing the 10th unit.
(b) (3 points) Find the actual cost of producing the 10th
unit.

If the total cost function for a product is C(x) = 9(x + 3)^3
dollars, where x represents the number of hundreds of units
produced, producing how many units will minimize average cost?
a) x= ?
b) Find the minimum average cost per hundred units.

If the total cost function for a product is C(x) = 8(x + 5)3
dollars, where x represents the number of hundreds of units
produced, producing how many units will minimize average cost? x =
hundred units Find the minimum average cost. (Round your answer to
two decimal places.) dollars per hundred units

The total cost of producing x units of a product is estimated by
the cost function
C = f(x) = 60x + 0.2x2 + 25,000
where C equals total cost measured in dollars.
a) This function is an example of what class of functions?
b) What is the cost associated with producing 25,000 units?
c) What is the cost associated with producing zero units? What
term might be used to describe this cost?

A company has a plant in Portland and a plant in Baltimore. The
firm is committed to produce a total of 146 units of a product each
week. The total weekly cost is given by
C(x,y)=(1/3)x^2+(1/3)y^2+57x+65y+1000, where x is the number of
units produced in Portland and y is the number of units produced in
Baltimore. How many units should be produced in each plant to
minimize the total weekly cost?

The total cost function for a product is
C(x) = 850
ln(x + 10) + 1800
where x is the number of units produced.
(a) Find the total cost of producing 300 units. (Round your
answer to the nearest cent.)
$
(b) Producing how many units will give total costs of $8500? (Round
your answer to the nearest whole number.)
units

Muzi Corporation produces three products at two different
plants. The cost of producing a unit at each plant is given in the
following table.
Product 1
Product 2
Product 3
Plant A
R5
R6
R8
Plant B
R8
R7
R10
Each plant has the capacity to produce a total of 10 000 units.
Demand for at least 6 000 units of product 1, at least 8 000 units
of product 2 and at least 5 000 units of product 3...
