Answer:
33.75%
Step-by-step explanation:
Let's assume a price is 100 dollars. It will be easier to calculate.
First, a mark down of 25%. That is:
25/100 = 0.25
0.25 * 100 = 25
Mark Down, so 100 - 25 = 75 dollars
It is worth 75 dollars now.
Next, 55% off, so
55/100 = 0.55
0.55 * 75 = 41.25
So, it is worth now 75 - 41.25 = 33.75 dollars
So, you end up paying 33.75 dollars off the original price of 100 dollars. That is 33.75% off original
