The book store is having a sale where all hardcover books are 20% off. Jamie also has a coupon for 15% off any fiction book. Jamie buys a hardcover fiction book that is priced $32.99. How much will Jamie save by buying the book on sale and using the coupon?

a. $10.56

b. $11.55

c. $13.20

d. $19.79

Price of the hardcover book bought by Jamie = $32.99

Percentage off given on hardcover books by the store = 20%

percentage off that Jamie gets on the coupon = 15%

Then

Total percentage off that Jamie gets on the book = (20 + 15) percent

= 35%

So

Amount of discount that Jamie gets on the book = (35/100) * 32.99

= 1154.65/100 dollars

= 11.55 dollars

So Jamie gets a total discount of $11.55 on the book. So the correct option among all the options given in the question is option "b".
