25 Mark'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 Cody, Henry and John paid = 15 u
Amount that Cody and Henry paid
= 15 u - 7 u
= 8 u
The amount that Cody and Henry each paid is the same.
Amount that Cody and Henry each paid
= 8 u ÷ 2
= 4 u
Cost of the present = 21 u
21 u = 105
1 u = 105 ÷ 21 = 5
Amount that Henry paid
= 4 u
= 4 x 5
= $20
Answer(s): $20
