John has $15. Japheth has $4
t more than John. Will has $2
t less than Japheth.
- Find the amount of money that Will has in terms of t.
- Find the total amount of money that the three boys have in terms of t.
- If t = 4, how much does Will have?
(a)
Amount that John has = $15
Amount that Japheth has = $(15 + 4
t)
Amount that Will has
= 15 + 4
t - 2
t = $(15 + 2
t)
(b)
Total amount that the three boys have
= 15 + 15 + 4
t + 15 + 2
t= 15 + 15 + 15 + 4
t + 2
t = $(45 + 6
t)
(c)
Amount that Will has
= 15 + 2
t= 15 + 2 x 4
= 15 + 8
= $23
Answer(s): (a) $(15 + 2
t) or $(2
t + 15); (b) $(45 + 6
t) or $(6
t + 45); (c) $23
