Zane has $19. Harry has $5
t more than Zane. Cole has $2
t less than Harry.
- Find the amount of money that Cole has in terms of t.
- Find the total amount of money that the three boys have in terms of t.
- If t = 7, how much does Cole have?
(a)
Amount that Zane has = $19
Amount that Harry has = $(19 + 5
t)
Amount that Cole has
= 19 + 5
t - 2
t = $(19 + 3
t)
(b)
Total amount that the three boys have
= 19 + 19 + 5
t + 19 + 3
t= 19 + 19 + 19 + 5
t + 3
t = $(57 + 8
t)
(c)
Amount that Cole has
= 19 + 3
t= 19 + 3 x 7
= 19 + 21
= $40
Answer(s): (a) $(19 + 3
t) or $(3
t + 19); (b) $(57 + 8
t) or $(8
t + 57); (c) $40
