Reggie has $20. Tommy has $5
v more than Reggie. Ivan has $2
v less than Tommy.
- Find the amount of money that Ivan has in terms of v.
- Find the total amount of money that the three boys have in terms of v.
- If v = 7, how much does Ivan have?
(a)
Amount that Reggie has = $20
Amount that Tommy has = $(20 + 5
v)
Amount that Ivan has
= 20 + 5
v - 2
v = $(20 + 3
v)
(b)
Total amount that the three boys have
= 20 + 20 + 5
v + 20 + 3
v= 20 + 20 + 20 + 5
v + 3
v = $(60 + 8
v)
(c)
Amount that Ivan has
= 20 + 3
v= 20 + 3 x 7
= 20 + 21
= $41
Answer(s): (a) $(20 + 3
v) or $(3
v + 20); (b) $(60 + 8
v) or $(8
v + 60); (c) $41
