3 children have a total of $3350.
Adam has $380 more than Bryan.
Bryan has 5 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 = 5 u
Amount that Adam has = 5 u + 380
Total amount that Adam, Bryan and Charlie
= 1 u + 5 u + 5 u + 380
= 11 u + 380
11 u + 380 = 3350
11 u = 3350 - 380 = 2970
11 u = 2970
1 u = 2970 ÷ 11 = 270
Amount that Adam has
= 5 u + 380
= 5 x 270 + 380
= 1350 + 380
= $1730
(b)
Amount that Bryan has
= 5 u
= $1350
(c)
Amount that Charlie has
= 1 u
= $270
Answer(s): (a) $1730; (b) $1350; (c) $270
