Answer:
-22%
Step-by-step explanation:
The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.
670.80 - 860 = -189.2
-189.2/860 = -0.22
-0.22*100 = -22%

When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators. To add the fractions with unlike denominators, rename the fractions with a common denominator. So you could find the lowest common multiple and multiply the numerator and denomenator by it and then you can carry on with the rest of the equation. If this doesn’t make sense and you need these information for an equation I suggest you take a picture of it and upload it so someone can help you with it specifically
