what percent did the book decrease in price?

Answer 1

Answer:

38%

Step-by-step explanation:

Original price = $ 80

Price after reduction = $ 49.60

Reduction = 80 - 49.60  = $30.40

Percentage of decrease = $\frac{reduction price}{original price}*100$

                                         $= \frac{30.40}{80}*100\\\\=\frac{3040}{80}$

                                          =  38%

Answer:

38%
