Perry has $9. David has $4
m more than Perry. Julian has $2
m less than David.
- Find the amount of money that Julian 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 Julian have?
(a)
Amount that Perry has = $9
Amount that David has = $(9 + 4
m)
Amount that Julian has
= 9 + 4
m - 2
m = $(9 + 2
m)
(b)
Total amount that the three boys have
= 9 + 9 + 4
m + 9 + 2
m= 9 + 9 + 9 + 4
m + 2
m = $(27 + 6
m)
(c)
Amount that Julian has
= 9 + 2
m= 9 + 2 x 6
= 9 + 12
= $21
Answer(s): (a) $(9 + 2
m) or $(2
m + 9); (b) $(27 + 6
m) or $(6
m + 27); (c) $21
