- If a = 7, how much does Harry have?
(a)
Amount that Simon has = $12
Amount that Fred has = $(12 + 4
a)
Amount that Harry has
= 12 + 4
a - 2
a = $(12 + 2
a)
(b)
Total amount that the three boys have
= 12 + 12 + 4
a + 12 + 2
a= 12 + 12 + 12 + 4
a + 2
a = $(36 + 6
a)
(c)
Amount that Harry has
= 12 + 2
a= 12 + 2 x 7
= 12 + 14
= $26
Answer(s): (a) $(12 + 2
a) or $(2
a + 12); (b) $(36 + 6
a) or $(6
a + 36); (c) $26
