(a)
Amount that Michael has = $8
Amount that Tom has = $(8 + 4
a)
Amount that Carl has
= 8 + 4
a - 2
a = $(8 + 2
a)
(b)
Total amount that the three boys have
= 8 + 8 + 4
a + 8 + 2
a= 8 + 8 + 8 + 4
a + 2
a = $(24 + 6
a)
(c)
Amount that Carl has
= 8 + 2
a= 8 + 2 x 6
= 8 + 12
= $20
Answer(s): (a) $(8 + 2
a) or $(2
a + 8); (b) $(24 + 6
