(a)
Number of beads that Julie won from Gillian
=
15 x 40
= 8
Number of beads that Julie lost to Jaslyn
=
58 x 40
= 25
Number of beads that Julie won from Gillian
=
14 x 40
= 10
Number of beads that Julie had in the end
= 40 + 8 - 25 + 10
= 33
(b)
Number of beads that Gillian had at first
= 1 u + 10 + 25 + 8
= 33 + 10 + 25 + 8
= 76
Answer(s): (a) 33 ; (b) 76
