Marginal cost $60; 120 items cost $9500 to produce. The linear cost function is

C(x) = $60 + ($79.17/unit)x

Step-by-step explanation:

The linear cost function is represented by a straight line with slope $60/unit and y-intercept $60:

C(x) = $60 + ($9500/120 units)x, or

C(x) = $60 + ($79.17/unit)x

answer: 12

step-by-step explanation:

because yes

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
