This is the formula.
% Decrease = Decrease/Old Price x 100%
Since the store “decreases” 15%, that means that …
$120 is 85% of the original price.
120 = 85% x the original price
so,
the original price = 120 รท 85% = 141.18 [rounded to the cents]
To figure out this problem you must use a percent equation to find the actual discount.
If ‘d’ represents the original price then
d=0.15(120)
0.15*120=18
So the actual discount is $18
To find the orginal price, you must add the discount with the sale price, so
$120 + $18 = $138
The original price is $138
