a dog walker and he charges $10 to come to my house, $2 per mile walked. she charged you 16 dollars. Which equation could I use to determine how far she walked you dog.
16 + 10 = 2m
2m + 10 = 16***
16 + 2m = 10
2m - 10 = 16
The correct equation to determine how far the dog walker walked your dog would be:
Distance (miles) = (Total cost - Fixed cost) / Cost per mile
In this case, the fixed cost is $10 (the charge to come to your house) and the cost per mile is $2.
Therefore, the equation would be:
Distance (miles) = (16 - 10) / 2
Distance (miles) = 6 / 2
Distance (miles) = 3
So the dog walker walked your dog for 3 miles.
