3 children have a total of $2920.
Adam has $330 more than Charlie.
Charlie has 3 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 = 3 u
Amount that Adam has = 3 u + 330
Total amount that Adam, Charlie and Bryan
= 1 u + 3 u + 3 u + 330
= 7 u + 330
7 u + 330 = 2920
7 u = 2920 - 330 = 2590
7 u = 2590
1 u = 2590 ÷ 7 = 370
Amount that Adam has
= 3 u + 330
= 3 x 370 + 330
= 1110 + 330
= $1440
(b)
Amount that Charlie has
= 3 u
= $1110
(c)
Amount that Bryan has
= 1 u
= $370
Answer(s): (a) $1440; (b) $1110; (c) $370
