The cost of producing x hundred items is given by the equation C(x) = x2 – 3x + 7 and the revenue generated from sales of x hund
Goryan [66]

Answer:

At x = 2 and 10.

Step-by-step explanation:

Given : The cost of producing x hundred items is given by the equation C(x) = x^2-3x + 7

The revenue generated from sales of x hundred units is given by the equation R(x) = -x^2 + 21x-33

To Find :What values of x will the company break even?

Solution:

Cost function : C(x) = x^2-3x + 7

Revenue function : R(x) = -x^2 + 21x-33

Now to find the company break even :

-x^2 + 21x-33= x^2-3x + 7

24x= 2x^2+40

12x= x^2+20

x^2-12x+20=0

x^2-10x-2x+20=0

x(x-10)-2(x-10)=0

(x-2)(x-10)=0

So, x = 2,10

Hence the company break even at x = 2 and 10.

D) If C.P. - Rs 100, S.P. Rs 80, then loss percent​
AfilCa [17]

Step-by-step explanation:

Selling price = Rs.80

Cost price = Rs.100

here, CP > SP

Now...

Loss ( L ) = CP - SP

= RS.100 - 80

= Rs.20

Now...

loss \: percent \:  =  \frac{loss}{CP}  \times 100%

=  \frac{2000}{100}  \\

= 20 %
