Dear All, I am trying to help my daughter and found the solution to this problem 35&49 but can't find a way of putting this in a plain math formula to explain logically.
If Mark sells 7 cars to John, John will have as many car as Mark.
On the other hand if John sells 7 car to Mark, Mark will have twice as many car as John.
Many thanks for your help.
