3 children have a total of $3390.
Bryan has $310 more than Adam.
Adam has 3 times as much as Charlie.
- How much does Bryan have?
- How much does Adam 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 Adam has = 3 u
Amount that Bryan has = 3 u + 310
Total amount that Bryan, Adam and Charlie
= 1 u + 3 u + 3 u + 310
= 7 u + 310
7 u + 310 = 3390
7 u = 3390 - 310 = 3080
7 u = 3080
1 u = 3080 ÷ 7 = 440
Amount that Bryan has
= 3 u + 310
= 3 x 440 + 310
= 1320 + 310
= $1630
(b)
Amount that Adam has
= 3 u
= $1320
(c)
Amount that Charlie has
= 1 u
= $440
Answer(s): (a) $1630; (b) $1320; (c) $440
