conversations.value: Let's let "x" be the original number of dolls in Lucy's doll collection.
  Then, 2 dolls equals an increase of 25%, and this can be written as x*0.25=2.
  Solving for x we get x=2/0.25=8 dolls in Lucy's original collection.
  After the gift of two new dolls, Lucy's collection contains 8+2=10 dolls.
