Answer:
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
