Uncle Joe made chocolate chip cookies. Peter ate fifty percent of them right away. Jack ate fifty percent of what was left. Fourteen cookies remain. How many cookies did Uncle Joe make?

Let J be the number that Uncle Joe started with

 

And we have that

 

J ( .50) (.50) =  14

 

J * .25  = 14

 

J =  14 /  .25  =    56

 

Proof

When  Peter ate 1/2 of these 56.... 28 remain

When Jack  ate 1/2 of these 28....  14 remain
