Brooke earns eight dollars per hour for babysitting one child when she cleans the kitchen. She earns an extra five dollars if Brooke planned to clean the kitchen which equation represents how much Brooke would earn babysitting.

Let's call the total amount Brooke would earn by babysitting as E and the number of hours she works as h.

Then, if she cleans the kitchen, Brooke would earn 8 dollars per hour, so the additional amount she would earn is 8h.

If she planned to clean the kitchen, she would earn an extra 5 dollars, so we can represent this as 5.

Therefore, the equation that represents how much Brooke would earn babysitting is:
E = 8h + 5
