(a)
Amount that Zane has = $11
Amount that Luke has = $(11 + 5
a)
Amount that Bryan has
= 11 + 5
a - 2
a = $(11 + 3
a)
(b)
Total amount that the three boys have
= 11 + 11 + 5
a + 11 + 3
a= 11 + 11 + 11 + 5
a + 3
a = $(33 + 8
a)
(c)
Amount that Bryan has
= 11 + 3
a= 11 + 3 x 4
= 11 + 12
= $23
Answer(s): (a) $(11 + 3
a) or $(3
a + 11); (b) $(33 + 8
a) or $(8
a + 33); (c) $23
