(a)
Number of beads that Elyse won from Fanny
=
25 x 70
= 28
Number of beads that Elyse lost to Zara
=
37 x 70
= 30
Number of beads that Elyse won from Fanny
=
15 x 70
= 14
Number of beads that Elyse had in the end
= 70 + 28 - 30 + 14
= 82
(b)
Number of beads that Fanny had at first
= 1 u + 14 + 30 + 28
= 82 + 14 + 30 + 28
= 154
Answer(s): (a) 82 ; (b) 154
