Question

If an item that had already been discounted at 25%, was mistakenly sold at a discount of 30%, what is the original price it was sold for $400?

Answer 1

Answer:

761.9 $

Step-by-step explanation:

Let say the original price of item = 100 C

item discounted at 25 %

discount = (25/100)100C = 25C

price after discount= 100C -25C = 75C

mistakenly sold at a discount of 30%,

further discount= (30/100)75 = 22.5C

selling price= 75C -22.5C = 52.5C

sold for $400

=> 52.5C =400 $

1 C = 400/52.5

100C = 100 * 400/52.5

= 761.9 $
