Vincent has $17. Archie has $5
d more than Vincent. Ethan has $2
d less than Archie.
- Find the amount of money that Ethan has in terms of d.
- Find the total amount of money that the three boys have in terms of d.
- If d = 4, how much does Ethan have?
(a)
Amount that Vincent has = $17
Amount that Archie has = $(17 + 5
d)
Amount that Ethan has
= 17 + 5
d - 2
d = $(17 + 3
d)
(b)
Total amount that the three boys have
= 17 + 17 + 5
d + 17 + 3
d= 17 + 17 + 17 + 5
d + 3
d = $(51 + 8
d)
(c)
Amount that Ethan has
= 17 + 3
d= 17 + 3 x 4
= 17 + 12
= $29
Answer(s): (a) $(17 + 3
d) or $(3
d + 17); (b) $(51 + 8
d) or $(8
d + 51); (c) $29
