Answer:
25% off means the cost to the customer will be 225
25% of means take 25% * 300 (which is 75) and that is the going price.
Explanation:
25% off 300 means that you take 300, and find out what 25% of that is.
25/100 * 300 = 75
Now that means that the customer gets to take 25% off the selling price which is 300 - 75 = 225.
The new price is $225.00
25% of 300 has an entirely different meaning. It means that "what is 25% times 300"
That's the same 75 dollars. Only this time, that's the answer. Of means multiply.
