To find the percentage of a whole part, the percentage must 1st be changed into a decimal and then multiplied by the whole part. In this case we have:
25 percent, it is changed to (.25).
25% of 20 dollars is .25(20.00) = $5.00
Now subtract the 5 dollars from the 20 to find the purchase price.
$20.00-$5.00= $15.00 is the purchase price.
Method 2.
In this case, it might be easier, however, if you just understand that 25% is a 1/4 or one quarter.
So a quarter of 20 is 5 since 5x4 =20
We can say write away, without a calculator, that the answer is $15. ( since 20-5 is 15)
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
12 dollars
9 dollars.
25 percent off of 36 dollars would be 9 dollars off.
80% of $25 is $20, so 80% off would be $5.
25 percent of 18 dollars is 18*25/100 = 4.50 dollars So 25% off of 18 dollars is 13.50 dollars
5 dollars.
20 dollars
$5.00
Subtracting 25 percent from 25 dollars gives 25 x (1 - (25/100)) = $18.75
9 dollars.
12 dollars
$20-25% is easy to answer. first turn the percent into a decimal. It would then become .25 you multiply 20 by that decimal and get 5. So 25% - %20 would be 15 because 25% of 20 dollars is $5
To calculate 25 percent off of 24 dollars, first find 25 percent of 24. This is done by multiplying 24 by 0.25, which equals 6. Subtract this amount from the original price: 24 - 6 = 18. Therefore, 25 percent off of 24 dollars is 18 dollars.
25% off of $364 is about $273
