12 Glen's share : Total share = 1 : 2
The total amount paid for the present is repeated. Make the total amount the same. LCM of 5 and 3 is 15.
Amount that Carl, Andy and Simon paid = 10 u
Amount that Carl and Andy paid
= 10 u - 6 u
= 4 u
The amount that Carl and Andy each paid is the same.
Amount that Carl and Andy each paid
= 4 u ÷ 2
= 2 u
Cost of the present = 15 u
15 u = 135
1 u = 135 ÷ 15 = 9
Amount that Andy paid
= 2 u
= 2 x 9
= $18
Answer(s): $18
