3 children have a total of $1930.
Bryan has $130 more than Adam.
Adam has 4 times as much as Charlie.
- How much does Bryan have?
- How much does Adam have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Adam has = 4 u
Amount that Bryan has = 4 u + 130
Total amount that Bryan, Adam and Charlie
= 1 u + 4 u + 4 u + 130
= 9 u + 130
9 u + 130 = 1930
9 u = 1930 - 130 = 1800
9 u = 1800
1 u = 1800 ÷ 9 = 200
Amount that Bryan has
= 4 u + 130
= 4 x 200 + 130
= 800 + 130
= $930
(b)
Amount that Adam has
= 4 u
= $800
(c)
Amount that Charlie has
= 1 u
= $200
Answer(s): (a) $930; (b) $800; (c) $200
