Answer:
The total amount customer pays for the discounted book is $ 30.21 .
Step-by-step explanation:
As given
A customer buys a different book that has an original selling price of $38.
The book is discounted 25%.
25% is written in the decimal form
= 0.25
Discount amount = 0.25 × Selling price of the books
= 0.25 × 38
= $ 9.5
Cost of the books after getting discount of 25% = Selling price of the books - Discount amount
= $ 38 - $ 9.5
= $ 28.5
As given
The customer must pay a 6% sales tax on the discounted price of the book.
6% is written in the decimal form
= 0.06
Sales tax amount = 0.06 × Cost of the books after getting discount of 25% .
= 0.06 × 28.5
= $ 1.71
Thus
Total amount pays by the customer for the books = Sales tax amount + Cost of the books after getting discount of 25%.
= $ 1.71 + $ 28.5
= $ 30.21
Therefore the total amount customer pays for the discounted book is $ 30.21 .
Since 90 degree is 1/4 of a circle, the area will be 1/4 th area of the full circle.
The radius is given by, r = 8 ft, therefore, the area of the full circle is,
Therefore, the area of the sector is,
