Noa was paid a 25 percent commission for selling a used car. percents total 100% if she was paid $1,631.24, what was the selling price of the car?

If $1,631.24 is 25% than the selling price of the car would be exactly $6,524.96

If Noa was paid 25% the equivalent of $1631.24, then what is the total selling price of the used car? Let us consider that 25% is the 4th part of 100% (1/4). So from the given amount of $1631.24,  which in this case was the 25% commission paid to her, let us multiply the amount to 4 that will give us; 

1631.24 x 4 = 6524.96

So, we may conclude that the total selling price of the car is $6524.96, or we can simply take the process of getting the percentage of one amount by reversing the process. Here is an example; if we are to get the 25% of the total amount of 6524.96 then it should be written this way:

6524.96 x 25 = 163,124 then click on the symbol % will give you 1631.24 as a result. However, in some cases that you cannot find the symbol % then we can compute it this way: 6524.96 x .25 = 1631.24. Yet in this case, the given is 25% then we'll just have to reverse the formula like this: 

1631.24 / .25 will give us the amount of the total selling price, $6524.96

It’s option c for sure

The answer should be b.
