Michael has $14. Tommy has $5
i more than Michael. Albert has $2
i less than Tommy.
- Find the amount of money that Albert has in terms of i.
- Find the total amount of money that the three boys have in terms of i.
- If i = 7, how much does Albert have?
(a)
Amount that Michael has = $14
Amount that Tommy has = $(14 + 5
i)
Amount that Albert has
= 14 + 5
i - 2
i = $(14 + 3
i)
(b)
Total amount that the three boys have
= 14 + 14 + 5
i + 14 + 3
i= 14 + 14 + 14 + 5
i + 3
i = $(42 + 8
i)
(c)
Amount that Albert has
= 14 + 3
i= 14 + 3 x 7
= 14 + 21
= $35
Answer(s): (a) $(14 + 3
i) or $(3
i + 14); (b) $(42 + 8
i) or $(8
i + 42); (c) $35
