Lynne will charge $20.75 to walk each of the 8 dogs. You see, there is a constant pattern of $2.75 between each dog as the number of them gets higher and higher
For example:
40.00-37.25= 2.75
37.25- 34.50=2.75
To get this answer, you just had to keep subtracting 2.75 until you got to 8 dogs. Hope this helps! Have a blessed day!!
