Logan dislikes horses, but he opened the ranch because he heard it was a lucrative business and he wanted to make money.

Logan anticipates that as a result of these changes, his horse ranch will generate a profit in the next year or two. This year, Logan hired his brother, Luke, to work at the horse ranch. Logan pays Luke $500/hr to clean the horse stalls. Logan also hired his best friend, Lucy, to do Logans grocery shopping and other personal errands. He pays Lucy $15/hr.
