You can put this solution on YOUR website!
call the set-up fee s
Call the hourly fee h
total cost = (hourly fee)x(hrs) + set-up fee
For Gina:
230+=+h%2A5+%2B+s
(1) 5h+%2B+s+=+230
For Lori:
125+=+h%2A2+%2B+s
(2) 2h+%2B+s+=+125
Subtract (2) from (1)
(1) 5h+%2B+s+=+230
(2) -2h+-+s+=+-125
3h+=+105
h+=+35
The hourly rental fee is $35
