Hi All,
We're told that a retail appliance store priced a video recorder at 20 percent above the wholesale cost of $200 and a store employee applied the 10 percent employee discount to the retail price to buy the recorder. We're asked for the total price the employee paid for the recorder. The math behind this question can be done in a couple of different ways. You can actually do just a little math - and use the 'spread' of the answer choices to your advantage.
The 20% markup in the wholesale cost can be referred to as (1.2)
The 10% employee discount can be referred to as (0.9), since the employee is paying 90% of the normal retail price.
Thus, the total price paid that the employee paid for the video recorder would be ($200)(1.2)(0.9)
(1.2)(0.9) = 1.08, meaning that the employee paid 8% more than the retail price. Since 10% of $200 = $20, the employee paid a little less than $220. There's only one answer that fits...
