Pierre has $16. Elijah has $5
c more than Pierre. Ivan has $2
c less than Elijah.
- Find the amount of money that Ivan has in terms of c.
- Find the total amount of money that the three boys have in terms of c.
- If c = 5, how much does Ivan have?
(a)
Amount that Pierre has = $16
Amount that Elijah has = $(16 + 5
c)
Amount that Ivan has
= 16 + 5
c - 2
c = $(16 + 3
c)
(b)
Total amount that the three boys have
= 16 + 16 + 5
c + 16 + 3
c= 16 + 16 + 16 + 5
c + 3
c = $(48 + 8
c)
(c)
Amount that Ivan has
= 16 + 3
c= 16 + 3 x 5
= 16 + 15
= $31
Answer(s): (a) $(16 + 3
c) or $(3
c + 16); (b) $(48 + 8
c) or $(8
c + 48); (c) $31
