14 Owen's share : Total share = 1 : 4
The total amount paid for the present is repeated. Make the total amount the same. LCM of 7 and 5 is 35.
Amount that Luis, Seth and Brandon paid = 28 u
Amount that Luis and Seth paid
= 28 u - 10 u
= 18 u
The amount that Luis and Seth each paid is the same.
Amount that Luis and Seth each paid
= 18 u ÷ 2
= 9 u
Cost of the present = 35 u
35 u = 280
1 u = 280 ÷ 35 = 8
Amount that Seth paid
= 9 u
= 9 x 8
= $72
Answer(s): $72
