Ethan has $11. Fabian has $5
f more than Ethan. Seth has $2
f less than Fabian.
- Find the amount of money that Seth 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 Seth have?
(a)
Amount that Ethan has = $11
Amount that Fabian has = $(11 + 5
f)
Amount that Seth has
= 11 + 5
f - 2
f = $(11 + 3
f)
(b)
Total amount that the three boys have
= 11 + 11 + 5
f + 11 + 3
f= 11 + 11 + 11 + 5
f + 3
f = $(33 + 8
f)
(c)
Amount that Seth has
= 11 + 3
f= 11 + 3 x 5
= 11 + 15
= $26
Answer(s): (a) $(11 + 3
f) or $(3
f + 11); (b) $(33 + 8
f) or $(8
f + 33); (c) $26
