3 children have a total of $2060.
Adam has $240 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 + 240
Total amount that Adam, Bryan and Charlie
= 1 u + 3 u + 3 u + 240
= 7 u + 240
7 u + 240 = 2060
7 u = 2060 - 240 = 1820
7 u = 1820
1 u = 1820 ÷ 7 = 260
Amount that Adam has
= 3 u + 240
= 3 x 260 + 240
= 780 + 240
= $1020
(b)
Amount that Bryan has
= 3 u
= $780
(c)
Amount that Charlie has
= 1 u
= $260
Answer(s): (a) $1020; (b) $780; (c) $260
