A single discount equal to multiple discounts of 22% and 15% is...
I have been struggling with this for a while.
+129840 The easiest way to see this is to imagine that something costs, lets say $100
A 22% discount means that the item now sells for 78% of its original cost = $78
And.......another 15% discount means that the item now sells for 85% of the $78 = $66.30
So the combined discount = (100 - 66.30)% = 33.7%
A simple method to figure this is : 1 - (1-.22)(1-.15) = .337 = 33.7%
