An online retailer is selling used books for $5.49 and you have $40 to spend. How many books can you buy if you must pay 8.5% sales taxes and an additional 10% of the total purchase price (with tax) for shipping?

He can buy 6 books

explanation: 8.5% of 5.49 is 0.46.  10% of 5.49 is 0.54.  0.54 + 0.46 is $1.00

5.49 + 1.00 = 6.49,  40 divided by 6.49 is 6.16 books, but because you cant buy a 16th of a book, he can only buy 6 books.

answer: 32.68
