Answer :
old price = 2400
new price = 2040
difference = 2400 - 2040 = 360
difference divided by old price = 360 / 2400 = .15
that is the rate of the difference.
300x250
new price = 2040
difference = 2400 - 2040 = 360
difference divided by old price = 360 / 2400 = .15
that is the rate of the difference.
