Since 520 represents 50%, or half of those that were surveyed, multiply 520 by 2 to get the total surveyed.
520 *2 = 1040

Mathematics

Original Price = Final Price / (100 - Discount)

So...

OP = 360 / 100 - 0.40
OP = 360 / 0.60
OP = 600

The original price is $600.

To check, do 600 - (600 * 0.40) in a calculator. You get 600 - 240 = 360, the discounted cost.
