I believe the percent may be 15% ($2,400 - 15% = $2,040)

[~Answer Explanation~}:
The percent of the difference is the rate of the difference * 100%
the percent of the difference = .15 * 100% = 15%
since the new price is less than the old price, that is the percent of the decrease.
(See if it'll work): $2,400- 15% = $2,040
And there's your answer <33
