Ahmad has $20. Owen has $4
y more than Ahmad. Seth has $2
y less than Owen.
- Find the amount of money that Seth has in terms of y.
- Find the total amount of money that the three boys have in terms of y.
- If y = 7, how much does Seth have?
(a)
Amount that Ahmad has = $20
Amount that Owen has = $(20 + 4
y)
Amount that Seth has
= 20 + 4
y - 2
y = $(20 + 2
y)
(b)
Total amount that the three boys have
= 20 + 20 + 4
y + 20 + 2
y= 20 + 20 + 20 + 4
y + 2
y = $(60 + 6
y)
(c)
Amount that Seth has
= 20 + 2
y= 20 + 2 x 7
= 20 + 14
= $34
Answer(s): (a) $(20 + 2
y) or $(2
y + 20); (b) $(60 + 6
y) or $(6
y + 60); (c) $34
