Question

Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Part A
Choose the equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount.

A. 20 + 3m = 5m
B. 20 = 3m + 5m
C. 20 + 5m = 3m
D. 20 + m = 8m
Part B

m =
miles

Answer 1

Answer:

A

Step-by-step explanation:

Answer 2

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: $20+3m$

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: $5m$

------------------------------------------------------------------------------------------

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.

$20+3m =5m$

Part B:

Solving for m;

$20+3m =5m$

$5m-3m=20$

=> $2m=20$

=> m = 10

Hence, both would charge the same amount for 10 miles.
