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