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