David earns money by walking dogs and answering surveys. He earns $10 a week for each dog he walks and $0.12 for each survey he answers. Last week, Emerson answered 100 surveys and earned $42.
Part A: Create an equation that will determine the number of dogs he walked. (3 points)
Part B: Solve this equation and show your steps. (6 points)
Part C: How many dogs did David walk last week? Write your answer in a complete sentence. (1 point)
David walks 10 dogs, because if he earns a dollar for each dog he walked that means he walked 10 to earn 10 dollars. I’m not good with sentences so I’m sorry if you do not understand.
