Answer:
The formula for calculating successive discounts on a single item is as follows:
Total discount = ( x + y - xy / 100 ) %
Total discount = (40 + 25 - 40*25/100)%
Total discount = (40 + 25 - 1000/100)%
Total discount = (40 + 25 - 10)%
Total discount = 55%
To illustrate this answer in an example, let’s say an item costs $100.00. The store is offering me 40% off the price:
40% * $100.00 = $40 off and yields a new price of $60
Now, let’s say that a separate additional discount of 25% is offered on the item. This discount would be taken against the new price of $60.00:
25% * $60.00 = $15 off and yields a new price of $45
Thus, two successive discounts taken against a $100.00 item leaves a final price of $45.00.
