b.9.25%
c.10.78%

Answer 1

43.70 / 40 = 1.0925

1.0925 - 1 = 0.0925 = 9.25%

answer: b.9.25%

Answer 2

Option b. 9.25%

Explanation:

Karen paid for a book = $43.70

The price of the book = $40

Sales tax on the book = 43.70 - 40.00

= $3.70

Sales tax rate =
`(3.70)/(40)` × 100

= 9.25%

Option b. 9.25%
