Jenson has $12. David has $4
r more than Jenson. Harry has $2
r less than David.
- Find the amount of money that Harry 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 Harry have?
(a)
Amount that Jenson has = $12
Amount that David has = $(12 + 4
r)
Amount that Harry has
= 12 + 4
r - 2
r = $(12 + 2
r)
(b)
Total amount that the three boys have
= 12 + 12 + 4
r + 12 + 2
r= 12 + 12 + 12 + 4
r + 2
r = $(36 + 6
r)
(c)
Amount that Harry has
= 12 + 2
r= 12 + 2 x 6
= 12 + 12
= $24
Answer(s): (a) $(12 + 2
r) or $(2
r + 12); (b) $(36 + 6
r) or $(6
r + 36); (c) $24
