Let R = REGULAR price of the item

Joey and receives an employee discount of 10 percent off the regular price of any item.
So, Joey pays 90% of the REGULAR price.
In other words, 0.9R = the DISCOUNT price that Joey actually pays

What is the regular price of an item that Joey purchases for $99?
We can write: 0.9R = $99
Solve: R = 99/0.9 = 990/9 = 110

Answer: E

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.

We can let n = the regular price of the item and create the equation:

0.9n = 99

n = 99/0.9 = 110
