3 children have a total of $1150.
Charlie has $340 more than Adam.
Adam has 4 times as much as Bryan.
- How much does Charlie have?
- How much does Adam 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 Adam has = 4 u
Amount that Charlie has = 4 u + 340
Total amount that Charlie, Adam and Bryan
= 1 u + 4 u + 4 u + 340
= 9 u + 340
9 u + 340 = 1150
9 u = 1150 - 340 = 810
9 u = 810
1 u = 810 ÷ 9 = 90
Amount that Charlie has
= 4 u + 340
= 4 x 90 + 340
= 360 + 340
= $700
(b)
Amount that Adam has
= 4 u
= $360
(c)
Amount that Bryan has
= 1 u
= $90
Answer(s): (a) $700; (b) $360; (c) $90
