Answer:
Let the dog is walked m miles.
Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked.
Equation becomes: [tex]20+3m[/tex]
Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Equation becomes: [tex]5m[/tex]
------------------------------------------------------------------------------------------
Part A:
The equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount.
[tex]20+3m =5m[/tex]
Part B:
Solving for m;
[tex]20+3m =5m[/tex]
[tex]5m-3m=20[/tex]
=> [tex]2m=20[/tex]
=> m = 10
Hence, both would charge the same amount for 10 miles.
