Harry has $14. Archie has $5
r more than Harry. Ryan has $2
r less than Archie.
- Find the amount of money that Ryan has in terms of r.
- Find the total amount of money that the three boys have in terms of r.
- If r = 5, how much does Ryan have?
(a)
Amount that Harry has = $14
Amount that Archie has = $(14 + 5
r)
Amount that Ryan has
= 14 + 5
r - 2
r = $(14 + 3
r)
(b)
Total amount that the three boys have
= 14 + 14 + 5
r + 14 + 3
r= 14 + 14 + 14 + 5
r + 3
r = $(42 + 8
r)
(c)
Amount that Ryan has
= 14 + 3
r= 14 + 3 x 5
= 14 + 15
= $29
Answer(s): (a) $(14 + 3
r) or $(3
r + 14); (b) $(42 + 8
r) or $(8
r + 42); (c) $29
