Nick had $86, David had $43 and John had four times the total amount of money Nick and David had. How much must John give to Nick and David so that each of them has an equal amount of money?
- Nick
- David
(a)
Total amount that Nick and David had
= 86 + 43
= $129
Amount that John had
= 4 x 129
= $516
Total amount that the 3 boys had
= 129 + 516
= $645
Amount that each of them must have so that each of them has an equal amount of money
= 645 ÷ 3
= $215
Amount that John must give to Nick
= 215 - 86
= $129
(b)
Amount that John must give to David
= 215 - 43
= $172
Answer(s): (a) $129; (b) $172
