3 children have a total of $3200.
Bryan has $110 more than Adam.
Adam has 2 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 = 2 u
Amount that Bryan has = 2 u + 110
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 3200
5 u = 3200 - 110 = 3090
5 u = 3090
1 u = 3090 ÷ 5 = 618
Amount that Bryan has
= 2 u + 110
= 2 x 618 + 110
= 1236 + 110
= $1346
(b)
Amount that Adam has
= 2 u
= $1236
(c)
Amount that Charlie has
= 1 u
= $618
Answer(s): (a) $1346; (b) $1236; (c) $618
