25 Justin's share : Total share = 2 : 5
The total amount paid for the souvenir is repeated. Make the total amount the same. LCM of 5 and 7 is 35.
Amount that Ivan, Seth and Fred paid = 25 u
Amount that Ivan and Seth paid
= 25 u - 7 u
= 18 u
The amount that Ivan and Seth each paid is the same.
Amount that Ivan and Seth each paid
= 18 u ÷ 2
= 9 u
Cost of the souvenir = 35 u
35 u = 420
1 u = 420 ÷ 35 = 12
Amount that Seth paid
= 9 u
= 9 x 12
= $108
Answer(s): $108
