On Saturday, Enrique charges $2 for every 1/6 hour he spends running errands. He earned $50 last Saturday. He picked up dry cleaning for Mrs.Abel for 4/6 hour,ran to the post office for Mr.Kovac for 1 1/6hours, and swept up the lobby of the building for the apartment manager for 5/6 hour. He got a $4 tip from Mr.Kovac. How long did it take him to walk Mrs.Camacho's dog and pick up her groceries? Show your work.
