(a)
Number of beads that Gabby won from Lucy
=
25 x 70
= 28
Number of beads that Gabby lost to Jade
=
47 x 70
= 40
Number of beads that Gabby won from Lucy
=
12 x 70
= 35
Number of beads that Gabby had in the end
= 70 + 28 - 40 + 35
= 93
(b)
Number of beads that Lucy had at first
= 1 u + 35 + 40 + 28
= 93 + 35 + 40 + 28
= 196
Answer(s): (a) 93 ; (b) 196
