At a pet store, it costs $5 to wash a cat and $7.50 to wash 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.

4 dogs

Step-by-step explanation:

If you let x equal the number of cats washed and y equal the number of dogs washed then you can make the equation:

5x+7.5y=60

You can then put the number of cats washed into the equation:

5(6)+7.5y=60

30+7.5y=60

7.5y=30

y=4

So 4 dogs were washed

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
