Oscar has $17. Mark has $5
c more than Oscar. Elijah has $2

- If c = 4, how much does Elijah have?
(a)
Amount that Oscar has = $17
Amount that Mark has = $(17 + 5
c)
Amount that Elijah has
= 17 + 5
c - 2
c = $(17 + 3
c)
(b)
Total amount that the three boys have
= 17 + 17 + 5
c + 17 + 3
c= 17 + 17 + 17 + 5
c + 3
c = $(51 + 8
c)
(c)
Amount that Elijah has
= 17 + 3
c= 17 + 3 x 4
= 17 + 12
= $29
Answer(s): (a) $(17 + 3
c) or $(3
c + 17); (b) $(51 + 8
c) or $(8
c + 51); (c) $29
