Amira manufactures jeans and has determined the marginal cost function. where q is the number of pair jeans produced . If margin

Alja [10]

Given
<span>c'(q)=dc/dq=0.006q^2-0.6q+70
Integrate marginal cost to get cost function
c(q)=0.002q^3-0.3q^2+70q+C (C is a constant)

Fixed cost = 2000 means that C=2000.
or
c(q)=</span>0.002q^3-0.3q^2+70q+2000

Average cost=c(q)/q, for q=200,
=(0.002*q^3-0.3*q^2+70*q+2000)/q
=20000/200
=100

Answer: Average cost is $100

How many solutions does 4(3x+2)=4(2x+3) +4x have?

Diano4ka-milaya [45]

Final Answer: No Solution. 4(3x + 2) = 4(2x + 3) + 4x has 0 solutions.

Steps/Reasons/Explanations:

Hey there! 8 = 12 would have No Solution because 8 doesn't equal 12. An example of 1 solution is 12 = 12.

Question: How many solutions does 4(3x + 2) = 4(2x + 3) + 4x have?

<u>Step 1</u>: Expand.

$12x + 8 = 8x + 12 + 4x$

<u>Step 2</u>: Simplify $8x + 12 + 4x$ to $12x + 12$ .

$12x + 8 = 12x + 12$

<u>Step 3</u>: Subtract $12x$ on both sides.

$8 = 12$

<u>Step 4</u>: Because $8 = 12$ is false, there is no solution.

No Solution
