How did you arrive at K = ___+1u+15? I am sorry I couldn’t understand that.

At 1st, Ken have 15 more than Lisa
If ken give 15 to Lisa, Lisa have 15 more than Ken.
On order to have 21 more than Ken, Ken should give 3 dollars to Lisa, Since ken give Lisa, Lisa will have 6 dollars more (as she get 3 and Ken less 3).

So is 3+3+15=21.
