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