Sam had $75, Bryan had $39 and Bobby had thrice the total amount of money Sam and Bryan had. How much must Bobby give to Sam and Bryan so that each of them has an equal amount of money?
- Sam
- Bryan
(a)
Total amount that Sam and Bryan had
= 75 + 39
= $114
Amount that Bobby had
= 3 x 114
= $342
Total amount that the 3 boys had
= 114 + 342
= $456
Amount that each of them must have so that each of them has an equal amount of money
= 456 ÷ 3
= $152
Amount that Bobby must give to Sam
= 152 - 75
= $77
(b)
Amount that Bobby must give to Bryan
= 152 - 39
= $113
Answer(s): (a) $77; (b) $113
