To find the number of units that gives break-even for the product, solve the equation R C. Round your answer to the nearest whol
Harrizon [31]

Answer:

The correct answer is D.

Step-by-step explanation:

Giving the following information:

R = 90x

Total cost= 35x + 17,000

x= is the number of units produced and sold

Now, we know that:

Unitary variable cost= 35

Fixed costs= 17,000

Selling price per unit= 90

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 17,000 / (90 - 35)

Break-even point in units= 309 units

For the expression: (− 1/x )× 1−x/1+x × x/x^2−1 <br> Simplify the expression.
Contact [7]

Answer:

<em>     The simplified answer is   1/(x+1)^{2} </em>

Step-by-step explanation:

     For the given expression: (− 1/x )× 1−x/1+x × x/x^2−1

     we need to simplify it

<em>      x^{2} -1 = (x+1)×(x-1)</em>

     eliminating x and x-1 from the given equation we get

     1/(x+1)^{2}

     The value of x can't be zero

     As we can't divide zero by zero

     The value of x can't be one

     As we can't divide zero by zero

<em>     The simplified answer is   1/(x+1)^{2} </em>

AlladinOne [14]

Answer:

Award Brainliest to this answer :)

Step-by-step explanation:

1 /  p + g = 150

g - 80 = p   =>  p - g = - 80

 

2 /  Adding the equations eliminates g and gives  2p = 70, p = 35

Back substituting to the 1st Equation;  35 + g = 150  =>  g = 115  

 

3 /  No, not if the stated conditions remain.
