Question

anonymous · Answer

The number of candy bars that Miss Jones has is represented by C.

You know that Marty has 9 more than 3 times the number C. Work backwards. 

1) Three times the number C can be written as 3C
2) Nine more than 3C can be written as 3C +9

Therefore, the equation is 3C + 9
