12 Cody's share : Total share = 1 : 2
The total amount paid for the souvenir is repeated. Make the total amount the same. LCM of 7 and 3 is 21.
Amount that Jeremy, Mark and Ken paid = 14 u
Amount that Jeremy and Mark paid
= 14 u - 6 u
= 8 u
The amount that Jeremy and Mark each paid is the same.
Amount that Jeremy and Mark each paid
= 8 u ÷ 2
= 4 u
Cost of the souvenir = 21 u
21 u = 147
1 u = 147 ÷ 21 = 7
Amount that Mark paid
= 4 u
= 4 x 7
= $28
Answer(s): $28
