Oliver has $12. Carl has $5
f more than Oliver. Albert has $2
f less than Carl.
- Find the amount of money that Albert has in terms of f.
- Find the total amount of money that the three boys have in terms of f.
- If f = 7, how much does Albert have?
(a)
Amount that Oliver has = $12
Amount that Carl has = $(12 + 5
f)
Amount that Albert has
= 12 + 5
f - 2
f = $(12 + 3
f)
(b)
Total amount that the three boys have
= 12 + 12 + 5
f + 12 + 3
f= 12 + 12 + 12 + 5
f + 3
f = $(36 + 8
f)
(c)
Amount that Albert has
= 12 + 3
f= 12 + 3 x 7
= 12 + 21
= $33
Answer(s): (a) $(12 + 3
f) or $(3
f + 12); (b) $(36 + 8
f) or $(8
f + 36); (c) $33
