Answer:
The total amount the customer spends on the discounted book is $30.21.
Step-by-step explanation:
According to the details provided
A different book with an original price of $38 was purchased by a customer.
The book received a discount of 25%.
The decimal form of 25%

= 0.25
Calculating the discount amount: 0.25 imes Price of the book
= 0.25 imes 38
= $9.50
Price after applying the 25% discount = Original price - Discount amount
= $38 - $9.50
= $28.50
As indicated
The customer has to pay a 6% sales tax on the discounted book's price.
6% in decimal form

= 0.06
Calculating the sales tax: 0.06 imes Cost after discount.
= 0.06 imes 28.50
= $1.71
Therefore
The total amount the customer pays for the book = Sales tax + Cost after discount.
= $1.71 + $28.50
= $30.21
Thus, the total payment made by the customer for the discounted book is $30.21.
