The amount of the discount = list price - discounted price = 1550 - 950 = 600
How much of a discount did Royal receive?
Use the equation p = w * %
p = the part of the whole
w = the whole amount
% = percent of the whole
600 = 1550 * %
% = 600/1550 = 2/5 = 0.387 = 38.7%
Royal received approximately a 39% discount off of the list price
