1 Explain why the factor 1.5 is broken into two numbers
in the model.

This is so it would be easier to calculate then just multiplying 1.5 since it is easier to multiply 1 separately then multiply 0.5 separately

Hope this Helps!!! :)

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

95.03 is the answer. hope this !
