15 Liam's share : Total share = 1 : 5
The total amount paid for the gift is repeated. Make the total amount the same. LCM of 14 and 6 is 42.
Amount that Oscar, David and Rael paid = 35 u
Amount that Oscar and David paid
= 35 u - 15 u
= 20 u
The amount that Oscar and David each paid is the same.
Amount that Oscar and David each paid
= 20 u ÷ 2
= 10 u
Cost of the gift = 42 u
42 u = 294
1 u = 294 ÷ 42 = 7
Amount that David paid
= 10 u
= 10 x 7
= $70
Answer(s): $70
