If Tim gives 6 stamps to Lynn, she will have 6 more stamps than him. However, Lynn must have 16 more stamps than Tim in the end. So, Tim has to give Lynn more stamps.
Number of more stamps that Tim has to give to Lynn
= (16 - 6) ÷ 2
= 10 ÷ 2
= 5
So after giving 6 stamps to Lynn, Tim has to give her another 5 more stamps so that she has 16 stamps more than him.
Total number of stamps that Lynn needs to get from Tim
= 6 + 5
= 11
Answer(s): 11
