Answer: RS 49.8

Step-by-step explanation:

Given the following :

Fixed cost = RS 4430

Break even point = 89 units

Recall:

Break even point in units = Fixed cost ÷ contribution margin

Therefore,

Contribution margin equals;

(Fixed cost ÷ break even point in units)

= 4430 / 89

= 49.775280

= RS 49.8

Answer:

a_0 = -8

a_1=-6

x^2 +y^2 -8x - 6y = 0

Step-by-step explanation:

The equation of the circle has the following form

x^2 + y^2 + a_0x + a_1y=0

The equation of the circle has the following form

We know that the circle goes through the following points

(1, 7)

(8, 6)

(7, -1).

Then we substitute the values of x and y in the equation

<u>For (1, 7)</u>

(1)^2 + (7)^2 + a_0(1) + a_1(7)=0

1 + 49 + a_0 + 7a_1=0

a_0 + 7a_1=-50    (1)

<u>For  (8, 6)</u>

(8)^2 + (6)^2 + a_0(8) + a_1(6)=0

64 + 36 + 8a_0 + 6a_1=0

8a_0 + 6a_1= -100    (2)

With these equations is enough to solve the system

a_0 + 7a_1=-50    (1)

8a_0 + 6a_1= -100    (2)

Multiply the equation (1) by -8 and add it to the equation (2)

-8a_0 - 56a_1=400    (1)

8a_0 + 6a_1= -100    (2)

-----------------------------------------------------

-50a_1 = 300\\\\a_1 = -6

Then

a_0 + 7(-6) = -50\\\\a_0 = -50+42\\\\a_0=-8

Finally the equation is:

x^2 +y^2 -8x - 6y = 0
