**CONCEPTS: **The basics of Profit/Loss have been applied in the question.

**SOLUTION:**

His cost of the car is $8,000.

15% of 8,000 =$1,200,

Hence the Selling price(SP) should be

=Cost Price(CP) +Profit

= $9,200.

We have to find a sticker price so that a 20% discount gives him $9,200 as SP

Let y be the sticker price.

If the sticker price is discounted 20%, then 80% of the sticker price remains.

So, we need to find y such that

0.8y=$9200.

=>y=$11,500.(OPTION D)
