3 children have a total of $2180.
Charlie has $230 more than Adam.
Adam has 6 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 = 6 u
Amount that Charlie has = 6 u + 230
Total amount that Charlie, Adam and Bryan
= 1 u + 6 u + 6 u + 230
= 13 u + 230
13 u + 230 = 2180
13 u = 2180 - 230 = 1950
13 u = 1950
1 u = 1950 ÷ 13 = 150
Amount that Charlie has
= 6 u + 230
= 6 x 150 + 230
= 900 + 230
= $1130
(b)
Amount that Adam has
= 6 u
= $900
(c)
Amount that Bryan has
= 1 u
= $150
Answer(s): (a) $1130; (b) $900; (c) $150
