Question

Karen paid 43.70 for a book. The price of the books was $40. What was the sales tax rate?

Answer 1

43.70 - 40 = 3.7

3.7 / 40 = 0.0925 = 9.25%

tax rate = 9.25%

Answer 2

Answer: 9.25%

Explanation:

Hi, to answer this first we have to calculate the amount of the tax paid, by subtracting the price of the book (40) to the total price paid (43.70)

43.70-40 = 3.7

So, $40 is the price of the book. It’s the 100% of the price. $40/100%

For 3.7 = 3.7/100

$40/100%= $3.7/x%

40/100 =3.7/x

x = 3.7/ (40/100)

x=9.25%
