i have no cule on this qusetion

Answer 3

okay well the total price that he paid for the book must be the original price of the book + tax on the original price of book

suppose the sales tax rate is \(x\)% then-

total price paid= original price+ tax on original price
\(23.54=22+ 22\times \large \frac{x}{100}\)

try solving for \(x\) from here =]
