So, im t trying to find the original price and sale price of a book for example and the amount of discount is 2.80 dollars and the percent paid was 60 percent and percent saved was 40 %, plz i just need the explanation of how to do it cause i got more of these problems

Okay, so since the discount is 60% of the price and it comes out to $2.8, we are going to form the following expression, where x is the original price.

60% of x = 2.8

Simply means: 60/100 * x = 2.8

You solve for x, which comes out to $4, which is your original price.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

is should be y = 5x

step-by-step explanation:

correct me if im wrong
