  1. Formula:
    Total worth in cents =
    10 cents x z coins + 5 cents x (z - 3 coins)      
        coin                         coin

    Total worth of coins = 10z + 5 (z - 3)
                                   = 10z + 5z - 15
                                   = 15z - 15
                                   = 15 (z - 1)


    Ans : C
