A book store is having a 30% off sale. Diary of a Wimpy Kid books are now $6.30 each. What was the original price of the books? Please HELP!!! I need a detailed answer. Explain how you got the answer, PLEASE!!
100%-30% is 70%. Therefore, $6.30 is 70% of the original answer. Write the ratio 6.3/x = 70/100 Cross multiply, and get 630=70x x=9 Therefore, The Diary of a Wimpy Kid book is $9.
