3 children have a total of $3890.
Adam has $150 more than Bryan.
Bryan has 5 times as much as Charlie.
- How much does Adam have?
- How much does Bryan 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 Bryan has = 5 u
Amount that Adam has = 5 u + 150
Total amount that Adam, Bryan and Charlie
= 1 u + 5 u + 5 u + 150
= 11 u + 150
11 u + 150 = 3890
11 u = 3890 - 150 = 3740
11 u = 3740
1 u = 3740 ÷ 11 = 340
Amount that Adam has
= 5 u + 150
= 5 x 340 + 150
= 1700 + 150
= $1850
(b)
Amount that Bryan has
= 5 u
= $1700
(c)
Amount that Charlie has
= 1 u
= $340
Answer(s): (a) $1850; (b) $1700; (c) $340
