Sagot :

The equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount is A. 20 + 3m = 5m

How to calculate the equation?

Let the dog miles be represented as m

Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. This will be:

20 + 0.3m

Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked. This will be:

5m

Therefore, the equation will be:

20 + 3m = 5m

5m - 3m = 20

2m = 20

Divide

m = 20/2

m = 10

Therefore, the correct option is A.
