Question

Suppose Brian is in the market for a used textbook and the campus bookstore is having a sale. If the initial price of the used book is $85 and the discounted price is $55 , what is the percentage change in the book price? Round your answer to two places after the decimal.

Answer 1

Answer:

35.29%

Explanation:

Data provided in the question:

Market price of the used book = $85

Discounted price = $55

Now,

The percentage change in the book price will be calculated as:

=$\frac{\textup{Market price - Discounted price}}{\textup{Market price}}\times100$

on substituting the respective values, we get

=$\frac{85-55}{85}\times100$

= 35.29%

Hence,

the percentage change in the book price is 35.29%
