3 children have a total of $1470.
Adam has $190 more than Charlie.
Charlie has 2 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 = 2 u
Amount that Adam has = 2 u + 190
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 190
= 5 u + 190
5 u + 190 = 1470
5 u = 1470 - 190 = 1280
5 u = 1280
1 u = 1280 ÷ 5 = 256
Amount that Adam has
= 2 u + 190
= 2 x 256 + 190
= 512 + 190
= $702
(b)
Amount that Charlie has
= 2 u
= $512
(c)
Amount that Bryan has
= 1 u
= $256
Answer(s): (a) $702; (b) $512; (c) $256
