Andy had $90, Fabian had $20 and Sean had twice the total amount of money Andy and Fabian had. How much must Sean give to Andy and Fabian so that each of them has an equal amount of money?
- Andy
- Fabian
(a)
Total amount that Andy and Fabian had
= 90 + 20
= $110
Amount that Sean had
= 2 x 110
= $220
Total amount that the 3 boys had
= 110 + 220
= $330
Amount that each of them must have so that each of them has an equal amount of money
= 330 ÷ 3
= $110
Amount that Sean must give to Andy
= 110 - 90
= $20
(b)
Amount that Sean must give to Fabian
= 110 - 20
= $90
Answer(s): (a) $20; (b) $90
