3 children have a total of $1880.
Adam has $340 more than Charlie.
Charlie has 5 times as much as Bryan.
- How much does Adam have?
- How much does Charlie have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Charlie has = 5 u
Amount that Adam has = 5 u + 340
Total amount that Adam, Charlie and Bryan
= 1 u + 5 u + 5 u + 340
= 11 u + 340
11 u + 340 = 1880
11 u = 1880 - 340 = 1540
11 u = 1540
1 u = 1540 ÷ 11 = 140
Amount that Adam has
= 5 u + 340
= 5 x 140 + 340
= 700 + 340
= $1040
(b)
Amount that Charlie has
= 5 u
= $700
(c)
Amount that Bryan has
= 1 u
= $140
Answer(s): (a) $1040; (b) $700; (c) $140
