Harry is a dog walker and he charges 15 dollars to come to my house, 2 dollars per mile walked. He charged me 19 dollars. Which equation could I use to determine howxfar he walked my dog.

A. 2m + 5 = 19
B.19 + 15 = 2m
C.19 + 2m =15
D.2m + 15 =15

What do you think?

uh the answer is A

To determine how far Harry walked your dog, you need to set up an equation based on the given information.

Let's break down the information provided:
- Harry charges $15 just to come to your house, regardless of the distance.
- On top of that, he charges $2 per mile for walking the dog.
- You were charged a total of $19.

Since the $15 charge is for coming to your house, the remaining $19 - $15 = $4 accounts for the dog-walking fee, which is based on the distance walked.

Let's represent the distance in miles with the variable 'm'. Since Harry charges $2 per mile, the dog was walked 'm' miles, and the cost for walking the dog would be 2m.

So, we can set up the equation:
2m (dog-walking fee) + $15 (house visit fee) = $19 (total charged)

Now, let's check which equation represents this information:
A. 2m + 5 = 19 - This equation has an unrelated term of "+ 5", so it is incorrect.
B. 19 + 15 = 2m - This equation has the fees on the left side and does not consider the total charged, so it is incorrect.
C. 19 + 2m = 15 - This equation has the fees switched on the left side and does not consider the total charged, so it is incorrect.
D. 2m + 15 = 15 - This equation only considers the dog-walking fee, but not the total charged, so it is incorrect.

The correct equation is: 2m + 15 = 19

Therefore, the answer is A. 2m + 15 = 19.
