Pierre has $19. Archie has $5
s more than Pierre. Oliver has $2
s less than Archie.
- Find the amount of money that Oliver has in terms of s.
- Find the total amount of money that the three boys have in terms of s.
- If s = 6, how much does Oliver have?
(a)
Amount that Pierre has = $19
Amount that Archie has = $(19 + 5
s)
Amount that Oliver has
= 19 + 5
s - 2
s = $(19 + 3
s)
(b)
Total amount that the three boys have
= 19 + 19 + 5
s + 19 + 3
s= 19 + 19 + 19 + 5
s + 3
s = $(57 + 8
s)
(c)
Amount that Oliver has
= 19 + 3
s= 19 + 3 x 6
= 19 + 18
= $37
Answer(s): (a) $(19 + 3
s) or $(3
s + 19); (b) $(57 + 8
s) or $(8
s + 57); (c) $37
