The amount of the discount is 20% of the original price, which is $45.

20% of x=45
.20x=45

Divide both sides by .20
%28.20x%29%2F.20=45%2F.20
x=450%2F2=225

The original price was $225. You saved $45, so you paid $180.

Check: If the original price was $225 less 20%, that would be a discount of $225*.2= $45, so you did indeed save $45.

20% of the price = 45$
100% of the price = (45/20)x100 = 225$
So the amount paid for the item = 225-45 = 180$
