3 children have a total of $1760.
Charlie has $440 more than Adam.
Adam has 5 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 = 5 u
Amount that Charlie has = 5 u + 440
Total amount that Charlie, Adam and Bryan
= 1 u + 5 u + 5 u + 440
= 11 u + 440
11 u + 440 = 1760
11 u = 1760 - 440 = 1320
11 u = 1320
1 u = 1320 ÷ 11 = 120
Amount that Charlie has
= 5 u + 440
= 5 x 120 + 440
= 600 + 440
= $1040
(b)
Amount that Adam has
= 5 u
= $600
(c)
Amount that Bryan has
= 1 u
= $120
Answer(s): (a) $1040; (b) $600; (c) $120
