Answer:33.75%
Explanation:
Let’s assume the price without discount is $100 .
Now from the information given , we have $100-0.25*$100 =0.75*$100
Which is 0.75 *$100= $75 is the price after the first discount .
0.75 - 0.55*$75= 0.45*$75
Now 0.45*75 = 33.75% which is the percentage of the original price .
