Tommy has $12. Sean has $4
m more than Tommy. Cody has $2
m less than Sean.
- Find the amount of money that Cody has in terms of m.
- Find the total amount of money that the three boys have in terms of m.
- If m = 6, how much does Cody have?
(a)
Amount that Tommy has = $12
Amount that Sean has = $(12 + 4
m)
Amount that Cody has
= 12 + 4
m - 2
m = $(12 + 2
m)
(b)
Total amount that the three boys have
= 12 + 12 + 4
m + 12 + 2
m= 12 + 12 + 12 + 4
m + 2
m = $(36 + 6
m)
(c)
Amount that Cody has
= 12 + 2
m= 12 + 2 x 6
= 12 + 12
= $24
Answer(s): (a) $(12 + 2
m) or $(2
m + 12); (b) $(36 + 6
m) or $(6
m + 36); (c) $24
