3 children have a total of $1030.
Bryan has $220 more than Adam.
Adam has 4 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 = 4 u
Amount that Bryan has = 4 u + 220
Total amount that Bryan, Adam and Charlie
= 1 u + 4 u + 4 u + 220
= 9 u + 220
9 u + 220 = 1030
9 u = 1030 - 220 = 810
9 u = 810
1 u = 810 ÷ 9 = 90
Amount that Bryan has
= 4 u + 220
= 4 x 90 + 220
= 360 + 220
= $580
(b)
Amount that Adam has
= 4 u
= $360
(c)
Amount that Charlie has
= 1 u
= $90
Answer(s): (a) $580; (b) $360; (c) $90
