Iwill mark them the brainliest answer if they get it right! the sale price of an item is four-fifths the original price of the item, x. which statement explains why both 4 5x and 0.8x can find the sale price of the item? a. the fraction 4/5is the same as the decimal 0.2. therefore, 4/5x can be written as 0.2x. b. multiplying by 4/5is the same as multiplying by 80%. c. multiplying by 5/4 is the same as multiplying by 0.8. d. the expressions are not equivalent.
