Question

Caitlin just bought a new book and a new game at Barnes & Noble. The total cost of both items was $37.95. If sales tax is 7%, how much money does Caitlin have to pay for her book with sales tax?

Answer 1

Ответ:

37.95*0.07=2.66

37.95-2.66=35.29

Answer 2

To calculate the cost of the book with sales tax, we need to determine the cost of the book before the tax is applied. Let's assume the cost of the book is x dollars.

Given that the total cost of both items (book and game) is $37.95, and the sales tax is 7%, we can set up the following equation:

x + 7% of x = $37.95

To find 7% of x, we multiply x by 0.07 (since 7% is equivalent to 0.07 as a decimal):

0.07 * x = 0.07x

Now, the equation becomes:

x + 0.07x = $37.95

Combine the x terms:

1.07x = $37.95

To find the value of x, divide both sides by 1.07:

x = $37.95 / 1.07

x ≈ $35.47

So, the cost of the book before sales tax is approximately $35.47. To find out how much Caitlin needs to pay for the book with sales tax, we need to add the sales tax to this amount.

Sales tax amount = 7% of $35.47 ≈ 0.07 * $35.47 ≈ $2.48

The final amount Caitlin needs to pay for her book with sales tax is:

$35.47 + $2.48 ≈ $37.95

Caitlin has to pay approximately $37.95 for her book with sales tax.
