At a pet store, it costs $5 to wash a cat and $7.50 to was a dog. last week , the store made $60 from washing cats and dogs. if 6 cats were washed, write and solve a linear equation to find how many dogs were washed

There was 4 cats washed

Step-by-step explanation:

1) Cats=x,  Dogs=y

2) Equation: 5x+7.50y=60

3) Substitute: 5 x 6 + 7.50y=60

4) Algebra: 30+7.50y=60

                   7.50y=30

                     y=4 dogs

4400

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
