The following graph represents the cost and revenue functions for custom made computers. how many computers have been sold at the break even point?
a.12
b.9
c.5
d.0

Option A. is the answer.

Step-by-step explanation:

In the graph attached red colored line is representing the cost function for the custom made computers.

Similarly green line is representing the revenue function.

Now we know break even point is no profit no loss point.

So to get the break even point we will get a common point lying on both the lines shown in the graph.

From the graph we get (12, 9) as the break even point, that comes after the sales of 12 computers.

Therefore, option A. 12 is the answer.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

mean, 40.6
