Find the original price of a suit if the sale price is $46 after a 20% discount. Round to two decimal places.
Let $x be the original price.
(1- 20%)x = 46
80%x = 46
0.8 x = 46
x = 46/ .8 = 460/8 = 57.5
The original price is $57.5
Do your teacher mean 'Round to 2 decimal places if necessary' ? Because I see that you don't need to do that.
