Justin has $9. Gabriel has $4
f more than Justin. Eric has $2
f less than Gabriel.
- Find the amount of money that Eric has in terms of f.
- Find the total amount of money that the three boys have in terms of f.
- If f = 5, how much does Eric have?
(a)
Amount that Justin has = $9
Amount that Gabriel has = $(9 + 4
f)
Amount that Eric has
= 9 + 4
f - 2
f = $(9 + 2
f)
(b)
Total amount that the three boys have
= 9 + 9 + 4
f + 9 + 2
f= 9 + 9 + 9 + 4
f + 2
f = $(27 + 6
f)
(c)
Amount that Eric has
= 9 + 2
f= 9 + 2 x 5
= 9 + 10
= $19
Answer(s): (a) $(9 + 2
f) or $(2
f + 9); (b) $(27 + 6
f) or $(6
f + 27); (c) $19
