At an appliance store, the price of a refrigerator is marked up 25% to $406.25. what was the price of the refrigerator before the markup? enter your answer in the box.

$304.69.

First, I calculated 25% of 406.25 by multiplying 406.25 by 0.25 (the percentage divided by 100).  This is precisely equal to 101.5625.  I then subtracted that number from our original, marked-up price.  I then rounded to the nearest penny.
