Shea and her best friend Kelly both babysit during the summer. Shea charges $4 per hour plus a $3 service fee, while Kelly charges $3.50 per hour plus a $6 service fee. Solve the system by substitution to find the number of hours, h, and the amount of pay, p, where they each earn the same amount.

4h+3=The Pay of Shea
3.5h +6= The pay of Kelly
4h+3=3.5h+6
     -3          -3
4h=3.5h+3
-3.5h
.5h=3
*2    *2
h=?
Then stick "h" into one of the original equations and solve for someones pay to get "p"
3.5(h)+6=p OR 4(h)+3 =p
