b = price of a book
0.065b = tax
2(b + 0.065b) = 42.49
a.The sales tax at a bookstore is 6.5%. How many books did the customer buy if she spent $42.49?
b.The sales tax at a bookstore is 6.5%. If a customer buys two of each book, how many different books can she buy with $42.49?
c.The cost of two books is 42.49. What is the sales tax if the cost of one book is 0.065?
d.The tax of a book is 0.065b whenever you buy two or more books. How many books can you buy for $42.49?

Best ResponseYou've already chosen the best response.1@tori72 Do you also agree that the amount of the tax, shown as '0.065b = tax' in the given information, represents the 6.5% sales tax on a book?

Best ResponseYou've already chosen the best response.1Yes, I'm here. Can you now see the meaning of the given equation and briefly explain it? 2(b + 0.065b) = 42.49

Best ResponseYou've already chosen the best response.0well if i distribute it i get 2b + 0.13 = 42.49 and solving for b gives me b = 21.18, so each book is 21.18

Best ResponseYou've already chosen the best response.1Correct. So you understand that the total cost of 2 books, including the sales tax on each of them, is $42.49.

Best ResponseYou've already chosen the best response.1Your equation 2b + 0.13 = 42.49 should be 2b + 0.13b = 42.49

Best ResponseYou've already chosen the best response.1Correct. But, once again, you appear to understand that the total cost of 2 books, including the sales tax on each of them, is $42.49. Is that correct?

Best ResponseYou've already chosen the best response.0is it not b? a customer can buy 2 books if they have 42.49 and each book costs 21.18

Best ResponseYou've already chosen the best response.1Option B says that the customer buys 2 of each book, meaning that if the customer buys only 2 books the books will be exactly the same title. Therefore to get 2 different books the customer would need to buy 4 books, 2 with the same title and 2 with another title.
