Simon had $70, Billy had $50 and Luis had five times the total amount of money Simon and Billy had. How much must Luis give to Simon and Billy so that each of them has an equal amount of money?
- Simon
- Billy
(a)
Total amount that Simon and Billy had
= 70 + 50
= $120
Amount that Luis had
= 5 x 120
= $600
Total amount that the 3 boys had
= 120 + 600
= $720
Amount that each of them must have so that each of them has an equal amount of money
= 720 ÷ 3
= $240
Amount that Luis must give to Simon
= 240 - 70
= $170
(b)
Amount that Luis must give to Billy
= 240 - 50
= $190
Answer(s): (a) $170; (b) $190
