In this case the answer is very simple. .
Step 01:
Data
rate discount = 37% = 0.37
sold price = $507
original price = ?
Step 02:
(original price * rate discount) = discount
sold price = original price - discount
507 = original price - (original price * rate discount)
original price = x
507 = x - (x * 0.37)
507 = x - 0.37 x
507 = 0.63 x
507 / 0.63 = x
804.76 = x
The answer is :
The original price was $804.76
