Question

the pet shelter had a dog wash as a fund - raise . they charged $7 per dog , and earned $63 . how many dogs did they wash ?

Answer 1

They washed 9 dogs. 63/7 = 9

Answer 2

If they charge $7 per dog and earned $63, then you can find how many dogs they washed by dividing 63 by 7.
63 / 7 = 9
The pet shelter washed 9 dogs.

You can check this by multiplying the answer for how many dogs they washed by the cost per dog.
9 • 7 = 63
So 9 is the correct answer.
