Ken has $13. Oliver has $4
m more than Ken. Archie has $2
m less than Oliver.
- Find the amount of money that Archie has in terms of m.
- Find the total amount of money that the three boys have in terms of m.
- If m = 6, how much does Archie have?
(a)
Amount that Ken has = $13
Amount that Oliver has = $(13 + 4
m)
Amount that Archie has
= 13 + 4
m - 2
m = $(13 + 2
m)
(b)
Total amount that the three boys have
= 13 + 13 + 4
m + 13 + 2
m= 13 + 13 + 13 + 4
m + 2
m = $(39 + 6
m)
(c)
Amount that Archie has
= 13 + 2
m= 13 + 2 x 6
= 13 + 12
= $25
Answer(s): (a) $(13 + 2
m) or $(2
m + 13); (b) $(39 + 6
m) or $(6
m + 39); (c) $25
