Question

an item that sells for $375 is put on sale for $120. what is the percent of discount?

Answer 1

(Sale Price) / (Original Price) 
$120/$375 
0.32 <---multiply by 100 to change to a percent 
0.32 * 100 
32% <---this is the difference of the two numbers 

(Original Percent Price - Difference in price) 
100% - 32% 
68% 

The percent of decrease is 68% 

Answer 2

375 * .68=255
375-255=120
answer=68%
