Ethan has $16. Lee has $4
j more than Ethan. John has $2
j less than Lee.
- Find the amount of money that John has in terms of j.
- Find the total amount of money that the three boys have in terms of j.
- If j = 6, how much does John have?
(a)
Amount that Ethan has = $16
Amount that Lee has = $(16 + 4
j)
Amount that John has
= 16 + 4
j - 2
j = $(16 + 2
j)
(b)
Total amount that the three boys have
= 16 + 16 + 4
j + 16 + 2
j= 16 + 16 + 16 + 4
j + 2
j = $(48 + 6
j)
(c)
Amount that John has
= 16 + 2
j= 16 + 2 x 6
= 16 + 12
= $28
Answer(s): (a) $(16 + 2
j) or $(2
j + 16); (b) $(48 + 6
j) or $(6
j + 48); (c) $28
