(a)
Number of beads that Rachel won from Shannon
=
35 x 40
= 24
Number of beads that Rachel lost to Fanny
=
58 x 40
= 25
Number of beads that Rachel won from Shannon
=
15 x 40
= 8
Number of beads that Rachel had in the end
= 40 + 24 - 25 + 8
= 47
(b)
Number of beads that Shannon had at first
= 1 u + 8 + 25 + 24
= 47 + 8 + 25 + 24
= 104
Answer(s): (a) 47 ; (b) 104
