Michael has $16. Asher has $5
r more than Michael. Cole has $2
r less than Asher.
- Find the amount of money that Cole has in terms of r.
- Find the total amount of money that the three boys have in terms of r.
- If r = 6, how much does Cole have?
(a)
Amount that Michael has = $16
Amount that Asher has = $(16 + 5
r)
Amount that Cole has
= 16 + 5
r - 2
r = $(16 + 3
r)
(b)
Total amount that the three boys have
= 16 + 16 + 5
r + 16 + 3
r= 16 + 16 + 16 + 5
r + 3
r = $(48 + 8
r)
(c)
Amount that Cole has
= 16 + 3
r= 16 + 3 x 6
= 16 + 18
= $34
Answer(s): (a) $(16 + 3
r) or $(3
r + 16); (b) $(48 + 8
r) or $(8
r + 48); (c) $34
