Luis had $90, Valen had $39 and John had five times the total amount of money Luis and Valen had. How much must John give to Luis and Valen so that each of them has an equal amount of money?
- Luis
- Valen
(a)
Total amount that Luis and Valen had
= 90 + 39
= $129
Amount that John had
= 5 x 129
= $645
Total amount that the 3 boys had
= 129 + 645
= $774
Amount that each of them must have so that each of them has an equal amount of money
= 774 ÷ 3
= $258
Amount that John must give to Luis
= 258 - 90
= $168
(b)
Amount that John must give to Valen
= 258 - 39
= $219
Answer(s): (a) $168; (b) $219
