Jiao works at least 36 h/wk. she earns $15 /h as a science tutor and $25 /h as a teacher. the number of hours jiao works as a teacher ( y ) is at least twice the number she works as a tutor ( x ). write a set of inequalities represents the constrai nts in this situation?

The set of inequalities that represent this situation is

 and

Step-by-step explanation:

Let

x -----> the number of hours Jiao works as a tutor in a week

y -----> the number of hours Jiao works as a teacher in a week

we know that

-----> inequality A

The solution of the inequality A is the shaded area above the solid line

-----> inequality B

The solution of the inequality B is the shaded area above the solid line  

The solution of the system of inequalities is the shaded area between the positive values of x and y

see the attached figure

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
