Wallet and Bag                 Watch –> (3/4) x 2u = (3/2)u

<—–  u———–>            <———–(3/2)u———->

[——–u———–][——–u———–][——–u———–]       

u + (3/2) u = (5/2)u = 350  => u = 350 x (2/5) = 140

Wallet           [p]

Bag                [p][p][p][p][p][p][p]

So 8p -> 140

=> p = 17.50

Hence Cost of Wallet is $17.50
