The answer to your question is:

bag = $ 264     wallet = $132     belt = $ 66

Step-by-step explanation:

Equation

              2bags + 3 wallets + 4 belts = $1188

Conditions

             1 bag = 2 wallets

             1 wallet = 2 belts           (1/2) wallet = 1 belt

Substitution in terms of wallets

            2(2 wallets) + 3 wallets + 4(1/2) wallet = $1188

            4 wallets + 3 wallets + 2 wallets = $1188

            9 wallets = $1188

            1 wallet = $1188 / 9

            1 wallet = $ 132

            1 bag = 2(132) = $ 242

            1 belt = (1/2) 132 = $ 66
