GRE 10- A computer store offers employees a 20% discount off the retail price.

A computer store offers employees a 20% discount off the retail price. If the store purchased a computer from the manufacturer for $1000 dollars and marked up the price 20% to the final retail price, how much would an employee save if he purchased the computer at the employee discount (20% off retail price) as opposed to the final retail price. A) $1,000 B) $960 C) $240 D) $200 E) $150

1. The original cost of the computer (from the store's perspective) was $1,000.
2. The retail price was 20% higher than the original cost, so multiply by 1.20; recall that 1.2 is equivalent to (100% + 20%):
   Retail Price: $1000(1.20) = $1,200.
3. The employee discount price was 20% lower than the retail price, so multiply by 0.80; recall that 0.8 is equivalent to (100% - 20%):
   Employee Discount Price: $1200(0.80) = $960.
4. Find the difference between the employee discount price and the retail price:
   $1200 - $960 = $240.
   The correct answer is C.
