PLSS ANSWER!! i dont understand how to do this ;-;. if you answer please explain how you got your answer.

Answer 1

Part A: 0.7(x)

Part B: 8.96/0.7 ---> (You can solve this by yourself)


For getting the answer, you can assume the regular price of the book is x. Then, the sale price would be x-0.3x, which is 0.7x

For part B, the price is 0.7 of the original. Dividing the number by 0.7 gets you the original price
