Laynee earns $8 per hour for walking her two neighbors' dogs each week. She also occasionally earns additional money for bathing one of the dogs.
Last week Laynee earned a total of $153. If this amount included $25 for bathing a dog, how many hours did Laynee spend walking her neighbors' dogs last week?
Responses
A 18 hours

D 16 hours
Explanation:
If Laynee earned $153 in total last week and $25 of that was from bathing a dog, then the amount she earned from walking the dogs would be $153 - $25 = $128.
At a rate of $8 per hour, Laynee would have to have worked $128 / $8 = 16 hours walking her neighbors' dogs.
