(a)
Number of beads that Dana won from Opal
=
23 x 72
= 48
Number of beads that Dana lost to Gabby
=
58 x 72
= 45
Number of beads that Dana won from Opal
=
14 x 72
= 18
Number of beads that Dana had in the end
= 72 + 48 - 45 + 18
= 93
(b)
Number of beads that Opal had at first
= 1 u + 18 + 45 + 48
= 93 + 18 + 45 + 48
= 204
Answer(s): (a) 93 ; (b) 204
