Question

What single discount is equivalent to two successive discounts of 15% and 7%?

Answer 1

1-(0.85)(0.93)

Answer 2

So, it must be approximately 21%

Answer 3

We can use an example where we have $100
\[(100*0.85)*(0.93)=79.05\]
So this is the same as a single discount of 20.95% since (100-79.05)
