3 children have a total of $2190.
Adam has $480 more than Charlie.
Charlie has 4 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 = 4 u
Amount that Adam has = 4 u + 480
Total amount that Adam, Charlie and Bryan
= 1 u + 4 u + 4 u + 480
= 9 u + 480
9 u + 480 = 2190
9 u = 2190 - 480 = 1710
9 u = 1710
1 u = 1710 ÷ 9 = 190
Amount that Adam has
= 4 u + 480
= 4 x 190 + 480
= 760 + 480
= $1240
(b)
Amount that Charlie has
= 4 u
= $760
(c)
Amount that Bryan has
= 1 u
= $190
Answer(s): (a) $1240; (b) $760; (c) $190
