Ryan has $20. Ethan has $5
k more than Ryan. Bryan has $2
k less than Ethan.
- Find the amount of money that Bryan has in terms of k.
- Find the total amount of money that the three boys have in terms of k.
- If k = 6, how much does Bryan have?
(a)
Amount that Ryan has = $20
Amount that Ethan has = $(20 + 5
k)
Amount that Bryan has
= 20 + 5
k - 2
k = $(20 + 3
k)
(b)
Total amount that the three boys have
= 20 + 20 + 5
k + 20 + 3
k= 20 + 20 + 20 + 5
k + 3
k = $(60 + 8
k)
(c)
Amount that Bryan has
= 20 + 3
k= 20 + 3 x 6
= 20 + 18
= $38
Answer(s): (a) $(20 + 3
k) or $(3
k + 20); (b) $(60 + 8
k) or $(8
k + 60); (c) $38
