Joey works at a clothing store and receives an employee discount of 10 percent off the regular price of any item. What is the regular price of an item that Joey purchases for $99?
A. $89.10
B. $108.90
C. $109.00
D. $109.90
E. $110.00
Since the discount = 10% = 1/10, and the resulting discount price is an integer value, the regular price must be a dollar value that is a multiple of 10.
The correct answer is
E.
