Andy has $17. Rael has $5
d more than Andy. Dylan has $2
d less than Rael.
- Find the amount of money that Dylan has in terms of d.
- Find the total amount of money that the three boys have in terms of d.
- If d = 6, how much does Dylan have?
(a)
Amount that Andy has = $17
Amount that Rael has = $(17 + 5
d)
Amount that Dylan 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 Dylan has
= 17 + 3
d= 17 + 3 x 6
= 17 + 18
= $35
Answer(s): (a) $(17 + 3
d) or $(3
d + 17); (b) $(51 + 8
d) or $(8
d + 51); (c) $35
