Seth has $10. Valen has $4
e more than Seth. Ivan has $2
e less than Valen.
- Find the amount of money that Ivan has in terms of e.
- Find the total amount of money that the three boys have in terms of e.
- If e = 5, how much does Ivan have?
(a)
Amount that Seth has = $10
Amount that Valen has = $(10 + 4
e)
Amount that Ivan has
= 10 + 4
e - 2
e = $(10 + 2
e)
(b)
Total amount that the three boys have
= 10 + 10 + 4
e + 10 + 2
e= 10 + 10 + 10 + 4
e + 2
e = $(30 + 6
e)
(c)
Amount that Ivan has
= 10 + 2
e= 10 + 2 x 5
= 10 + 10
= $20
Answer(s): (a) $(10 + 2
e) or $(2
e + 10); (b) $(30 + 6
e) or $(6
e + 30); (c) $20
