Tim has $13. Oscar has $5
t more than Tim. Albert has $2
t less than Oscar.
- Find the amount of money that Albert 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 Albert have?
(a)
Amount that Tim has = $13
Amount that Oscar has = $(13 + 5
t)
Amount that Albert has
= 13 + 5
t - 2
t = $(13 + 3
t)
(b)
Total amount that the three boys have
= 13 + 13 + 5
t + 13 + 3
t= 13 + 13 + 13 + 5
t + 3
t = $(39 + 8
t)
(c)
Amount that Albert has
= 13 + 3
t= 13 + 3 x 4
= 13 + 12
= $25
Answer(s): (a) $(13 + 3
t) or $(3
t + 13); (b) $(39 + 8
t) or $(8
t + 39); (c) $25
