If an item that originally sold for w dollars was marked up by u percent and then discounted by v percent, which of the following expressions represents the final price of the item?  Choose the most appropriate option
A) (10,000w + 100w(u – v) – uvw)/10,000
B) (10,000w + 100w(v – u) – uvw)/10,000
C) (100w(u – v) – uvw)/10000
D) (100w(v – u) – uvw)/10000
E) 10000 /(u – v)
Assume w=100, u=10, v=10. So final price is 99. Now put these value each option. Only option (10,000w + 100w(u – v) – uvw)/10,000 will give right answer.
