25 Will's share : Total share = 2 : 5
The total amount paid for the present is repeated. Make the total amount the same. LCM of 3 and 7 is 21.
Amount that Luis, Xavier and Albert paid = 15 u
Amount that Luis and Xavier paid
= 15 u - 7 u
= 8 u
The amount that Luis and Xavier each paid is the same.
Amount that Luis and Xavier each paid
= 8 u ÷ 2
= 4 u
Cost of the present = 21 u
21 u = 42
1 u = 42 ÷ 21 = 2
Amount that Xavier paid
= 4 u
= 4 x 2
= $8
Answer(s): $8
