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