Beforre giving, Laura :
Amount + $20
Before giving, Nixon :
Amount - $20
Difference = $40
So Laura had $40 more than Nixon at first
Now if Nixon gave $22 to Laura,
Nixon : Amount - $20 - $22
= Amount - $42
Laura : Amount + $20 + $22
= Amount + $42
Difference = $84
Since Laura would have twice as Nixon, she has more than Nixon by 1 time.
That means Nixon has $84 left and she has 2 x $84 = $168 left.
Laura's amount at first
= $168 - $22
= $146
Nixon's amount at first
= $84 + $22
= $106
