Mary has 92 blouses. She has 20% fewer than Susan. How many blouses does she have?

115

Step-by-step explanation:

20% is one fifth. If Mary has one fifth fewer than Susan, then she has 4 fifths of what Susan has. So 92 is 4 fifths of some number.

To find out what one fifth is, you can divide 92 by 4 because it is four fifths.

92/4 = 23

So one fifth of the number of blouses Susan has is 23. Now you can multiply 23 by 5 to get the total number of blouses Susan has.

23 * 5 = 115
