Mary earned 9 dollars for cleaning her room. The next day she decides to spend all of the 9 dollars to buy her boyfriend a birthday card. Then next week she earned 5 dollars for babysitting her brother. 
You start your journey from your house to the store and walk 5 blocks. After 5 blocks you take a bus 4 blocks. After getting what you need from the store you walk back to your house but realize you forgot something and walk back to the store from your house. After all of that walking you decide to take the bus home. What is the total distance you walked?
