Howard has $13. Dylan has $5
f more than Howard. Luke has $2
f less than Dylan.
- Find the amount of money that Luke 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 Luke have?
(a)
Amount that Howard has = $13
Amount that Dylan has = $(13 + 5
f)
Amount that Luke has
= 13 + 5
f - 2
f = $(13 + 3
f)
(b)
Total amount that the three boys have
= 13 + 13 + 5
f + 13 + 3
f= 13 + 13 + 13 + 5
f + 3
f = $(39 + 8
f)
(c)
Amount that Luke has
= 13 + 3
f= 13 + 3 x 5
= 13 + 15
= $28
Answer(s): (a) $(13 + 3
f) or $(3
f + 13); (b) $(39 + 8
f) or $(8
f + 39); (c) $28
