25 Eric's share : Total share = 2 : 5
The total amount paid for the gift is repeated. Make the total amount the same. LCM of 3 and 7 is 21.
Amount that Andy, Oscar and Fabian paid = 15 u
Amount that Andy and Oscar paid
= 15 u - 7 u
= 8 u
The amount that Andy and Oscar each paid is the same.
Amount that Andy and Oscar each paid
= 8 u ÷ 2
= 4 u
Cost of the gift = 21 u
21 u = 105
1 u = 105 ÷ 21 = 5
Amount that Oscar paid
= 4 u
= 4 x 5
= $20
Answer(s): $20
