    Tom's books cost him $57.9569 after the discount

    Step-by-step explanation:

    Step 1: Determine the initial cost of the books

    Initial cost of books=$65.86

    Step 2: Calculate discount amount

    Discount amount can be expressed as follows;

    discount amount=discount rate*initial cost of books

    where;

    discount rate=12%

    initial cost of books=$65.86

    replacing;

    discount amount = (12/100) * 65.86=7.9032

    discount amount=$7.9032

    Step 3: Cost after discount

    The cost after discount can be expressed as;

    Cost after discount=Initial cost-discount amount

    where;

    Initial cost=$65.86

    discount amount=$7.9032

    replacing;

    Cost after discount = (65.86-7.9032) = $57.9569

    Tom's books cost him $57.9569 after the discount
