The original price of the item will be $ 480.When there is 75% off on the original price.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The right question is
"Joyce saved $120 on an item that was 75 % off. What was the original price?"
Given data;
% off = 75
Amount saved $120
Let the original price of the item is x
75 % of x + $120 = x
0.75x+ 120 =x
0.25 x =120
x=120/0.25
x=480
Hence, the original price of the item will be $ 480.
