Lets begin answering this by giving you some tricks to helping with even percentages (5%, 10%, 20%, etc).
When dealing with percentages that include 10% (such as yours when it asks for 25%), you can find 10% of any number by simply moving the decimal point one place to the left.
10% of 34.00 would be 3.400 (which we can remove the insignificant digits) or 3.4.
Now we know what 10% is we can find what 25%.
10% + 10% = 3.4 + 3.4 = 6.8. This is 20% of 34.00. Now our next step is to find 5%. 5% is exactly half of 10% so we can figure this out by:
3.4 ÷ 2 = 1.7. Thus we now have 3.4 + 3.4 + 1.7 = 8.5.
Now we have 25% of 34.00. Off means to substact so:
34.00 - 8.50 = $25.50.
25 percent off of 36 dollars would be 9 dollars off.
25 percent of 18 dollars is 18*25/100 = 4.50 dollars So 25% off of 18 dollars is 13.50 dollars
Subtracting 25 percent from 25 dollars gives 25 x (1 - (25/100)) = $18.75
3375
9 dollars.
25 percent off of 36 dollars would be 9 dollars off.
25 percent of 18 dollars is 18*25/100 = 4.50 dollars So 25% off of 18 dollars is 13.50 dollars
850
Subtracting 25 percent from 25 dollars gives 25 x (1 - (25/100)) = $18.75
3375
9 dollars.
12 dollars
25% off of $364 is about $273
3 dollars off
25% off $25 = $25 - (0.25 x $25) = $18.75
It is 25 cents off 5 dollars.
25% off of 50 dollars = 75% of 50 dollars = 50*75/100 = 37.50 dollars
