Luke had $70, Zeph had $33 and Ivan had twice the total amount of money Luke and Zeph had. How much must Ivan give to Luke and Zeph so that each of them has an equal amount of money?
- Luke
- Zeph
(a)
Total amount that Luke and Zeph had
= 70 + 33
= $103
Amount that Ivan had
= 2 x 103
= $206
Total amount that the 3 boys had
= 103 + 206
= $309
Amount that each of them must have so that each of them has an equal amount of money
= 309 ÷ 3
= $103
Amount that Ivan must give to Luke
= 103 - 70
= $33
(b)
Amount that Ivan must give to Zeph
= 103 - 33
= $70
Answer(s): (a) $33; (b) $70
