Carly tutor students in math on the weekends and offers both 30 minute sessions and 60 minute sessions she earns $15 for each 30 minute session and $25 for each 60 minute session. If she earned $230 this past weekend and had x-thirty minute sessions and x-2 sixty minute sessions, what is the value of x

x=7

x-2 = 7-2 = 5

Step-by-step explanation:

30 minutes session=$15

60 minutes session=$25

Quantity of 30 minutes session=x

Quantity of 60 minutes session=x-2

Total earnings=$230

Let

30 minutes session=y

60 minutes session=z

PyQy + PzQz = 230

15(x) + 25(x-2)=230

15x + 25x - 50=230

40x=230+50

40x=280

Divide both sides by 40

x=280/40

= 7

x=7

x-2

= 7-2

= 5

650+35w>825+15w
