you know, yz... butting in to say you can't help is not much help.
The markup is the sales amount over the cost --
36,002.98 - 31,399.99 = 4,602.99
The percent markup is thus 4602.99/31399.99 = 14.66% based on cost
or 12.79% based on selling price
C + r*C = $36,002.98.
31,399.99 + r*31,399.99 = 36,002.98,
31,399.99r = 4602.99,
r = 0.147 = 14.7% markup.
