(a)
Number of beads that Rachel won from Joelle
=
45 x 35
= 28
Number of beads that Rachel lost to Jade
=
57 x 35
= 25
Number of beads that Rachel won from Joelle
=
15 x 35
= 7
Number of beads that Rachel had in the end
= 35 + 28 - 25 + 7
= 45
(b)
Number of beads that Joelle had at first
= 1 u + 7 + 25 + 28
= 45 + 7 + 25 + 28
= 105
Answer(s): (a) 45 ; (b) 105
