Astore owner paid $15 for a book she marked up the price of the the book by 40% to determine its selling price part a what is the selling price of the book? part b a customer buys a different book that has an original selling price of $38 the book is discounted 25% the costumer must pay 6% sales tax on the discounted price of the book .what is the total amount the customer must pay for the discounted book

Part A: $21 Part B: $30.21

Step-by-step explanation:

Part A: First, just multiply 15 to 40 divided by 100. 15 x 40/100

40/100= 0.4. 15 x 0.4=6. 15+6=$21

Part B: Discount the book by 25% and then add the sales tax which is 6% and then the answer would be $30.21.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
