Oliver has $19. Eric has $5
i more than Oliver. Albert has $2
i less than Eric.
- 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 = 4, how much does Albert have?
(a)
Amount that Oliver has = $19
Amount that Eric has = $(19 + 5
i)
Amount that Albert has
= 19 + 5
i - 2
i = $(19 + 3
i)
(b)
Total amount that the three boys have
= 19 + 19 + 5
i + 19 + 3
i= 19 + 19 + 19 + 5
i + 3
i = $(57 + 8
i)
(c)
Amount that Albert has
= 19 + 3
i= 19 + 3 x 4
= 19 + 12
= $31
Answer(s): (a) $(19 + 3
i) or $(3
i + 19); (b) $(57 + 8
i) or $(8
i + 57); (c) $31
