A dog walker charges $6 to come to your house and then $3 per mile walked. She charged you $15.
A: 6m + 3 = 15
B: 6m - 3 = 15
C: 3n - 6 = 15
D: 3n +6 =15
D is the answer because however many miles do you walk you are multiplied by three and then It’s just plus six to go to her house and then you would equal 15 because that was the amount at the end
