3 children have a total of $2500.
Adam has $120 more than Bryan.
Bryan has 3 times as much as Charlie.
- How much does Adam have?
- How much does Bryan have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Bryan has = 3 u
Amount that Adam has = 3 u + 120
Total amount that Adam, Bryan and Charlie
= 1 u + 3 u + 3 u + 120
= 7 u + 120
7 u + 120 = 2500
7 u = 2500 - 120 = 2380
7 u = 2380
1 u = 2380 ÷ 7 = 340
Amount that Adam has
= 3 u + 120
= 3 x 340 + 120
= 1020 + 120
= $1140
(b)
Amount that Bryan has
= 3 u
= $1020
(c)
Amount that Charlie has
= 1 u
= $340
Answer(s): (a) $1140; (b) $1020; (c) $340
