Question

How would you minus $20\% $ off of 60.00 dollars?

Answer 1

Hint:
As we can simply find the $20\% $ of 100 which is 20 and similarly, $40\% $ of 100 is 40 and so on. Now, for the given problem statement we can find easily 20% for 60.00 dollars. After finding the $20\% $ of 60.00 dollars we have to subtract it from 60.00 dollars.

Complete step by step solution:
The given problem statement is minus $20\% $ off of 60.00 dollars.
From the statement, we get the idea that we have to subtract $20\% $ off of 60.00 dollars. For finding the percentage we will divide the number by 100.
To find $20\% $ of 60 we will multiple 20 and 60 and then we will divide them with 100.
 $ = \dfrac{{20}}{{100}} \times 60$
 $ = 12$
So, now we know that $20\% $ of 60 is 12. Hence, we will subtract 12 from 60 as 12 is $20\% $ of 60.
$ \Rightarrow 60.00 - 12.00 = 48.00$

Therefore, minus $20\% $ off of 60.00 dollars will be 48.00 dollars.

Additional Information:
Whenever the denominator is 100 and the number is in the form of a fraction that means it is a percentage. When we divide by 100 that means we are turning percentage into decimal and we need to do the opposite we just need to multiply by 100.

Note:
There is an alternative way of solving this problem.
Suppose if you get $20\% $ discount on an item then you are only paying $80\% $ to buy that item.
$ \Rightarrow (100 - 20)\% = 80\% $
Therefore, we can simply find $80\% $ of 60. From the statement, we get the idea that we have to find the percentage of $80\% $ off of 60.00 dollars.
We know that for finding the percentage we will divide the number by 100. And to find $80\% $ of 60 we will multiple 80 and 60 and then we will divide them with 100.
 $ \Rightarrow \dfrac{{80 \times 60}}{{100}} = 48$
Therefore, minus $20\% $ off of 60.00 dollars will be 48.00 dollars.
