Charlie has $19. Ahmad has $5
f more than Charlie. Perry has $2
f less than Ahmad.
- Find the amount of money that Perry 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 Perry have?
(a)
Amount that Charlie has = $19
Amount that Ahmad has = $(19 + 5
f)
Amount that Perry has
= 19 + 5
f - 2
f = $(19 + 3
f)
(b)
Total amount that the three boys have
= 19 + 19 + 5
f + 19 + 3
f= 19 + 19 + 19 + 5
f + 3
f = $(57 + 8
f)
(c)
Amount that Perry has
= 19 + 3
f= 19 + 3 x 7
= 19 + 21
= $40
Answer(s): (a) $(19 + 3
f) or $(3
f + 19); (b) $(57 + 8
f) or $(8
f + 57); (c) $40
