3 children have a total of $3300.
Adam has $410 more than Charlie.
Charlie has 2 times as much as Bryan.
- How much does Adam have?
- How much does Charlie have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Charlie has = 2 u
Amount that Adam has = 2 u + 410
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 410
= 5 u + 410
5 u + 410 = 3300
5 u = 3300 - 410 = 2890
5 u = 2890
1 u = 2890 ÷ 5 = 578
Amount that Adam has
= 2 u + 410
= 2 x 578 + 410
= 1156 + 410
= $1566
(b)
Amount that Charlie has
= 2 u
= $1156
(c)
Amount that Bryan has
= 1 u
= $578
Answer(s): (a) $1566; (b) $1156; (c) $578
