12 Michael's share : Total share = 1 : 2
The total amount paid for the present is repeated. Make the total amount the same. LCM of 7 and 3 is 21.
Amount that Bryan, Lee and Billy paid = 14 u
Amount that Bryan and Lee paid
= 14 u - 6 u
= 8 u
The amount that Bryan and Lee each paid is the same.
Amount that Bryan and Lee each paid
= 8 u ÷ 2
= 4 u
Cost of the present = 21 u
21 u = 63
1 u = 63 ÷ 21 = 3
Amount that Lee paid
= 4 u
= 4 x 3
= $12
Answer(s): $12
