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".

The reporter forgot to multiply the decimal by 100, making it 25%
