Question

Tom bought $65.86 worth of books at the book fair. He got 12% discount since he volunteered at the fair. About how much did Tom's books cost after the discount?

Answer 1

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
