Question 251152
cost of the dog was $2.50


His monetary expenses were $.25 which means he made a profit of $3.75 - $2.50 - $.25 = $3.75 - $2.75 = $1.00


he spent a total of 4 hours in cleaning and caring for the dog.
he spent a total of 9 hours in trying to sell the dog.


his profit was $1.00 / 13 = $.076923077 per hour.


round that to the nearest penny and it becomes 8 center per hour which would be selection A.
