The pair is any numbers, 1 positive and one negative, that add up to -3.
Here is a sample;
(-5, 2)
Let, the original amount = x
First discount = x * 0.20 = 0.20x
Amount after first discount = x - 0.20x = 0.80x
Second discount = 0.80x * 0.15 = 0.12x
Amount after second discount = 0.80x - 0.12x = 0.68x
Difference would be: x-0.68x = 0.32x
So, Your Answer would be 32%
Hope this helps!
