You walk each dog 20 minutes.

For every 20 minutes you get 2 dollars.

You walked 42 dogs.

You claim you are a "smartmathman".

You should easily know it's 2 dollars per dog, since you walk a dog for 20 minutes and each 20 minutes is 2 dollars.

I was wondering if I should subtract the $45 or not. If it's just how much she made walking in gross income.
