Mariana received a bonus of $50 for working the day after ,plus his regular wage of 9.45 an hour .if his total wages for the day were 135.05 ,how many hours did he work ?

9 hours

Step-by-step explanation:

50+9.45 x=135.05

9.45 x=135.05-50=85.05

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
