Roger sells cars at Cheetham Auto. Last month he sold 6 new cars at an average price of 17,400 dollars and 16 “pre-owned” cars at an average price of 7,800 dollars. What was his sales average per vehicle last month? Explain your thinking.

Well, Sales average means the average price each vehicle is; so here's my explanation:

 

total cars Roger sold last month: 22

 

total new cars he sold: 6

 

total "pre-owned" cars he sold: 16

 

6/22 * 17400 + 16/22 * 7800 ≈ \(10418.18181812\)

 

 

And that's the answer.
