Answer:
He paid approximately $ 8694.783 for the car.
Explanation:
Let x be the price of car that dealer pay for the car,
Also, the markup percentage = 15 %,
Thus, the hike in the price = 15 % of the price paid by dealer
= 15 % of x


So, the sticker price of the car = The price paid by dealer + hike in the price
= x + 0.15x
= 1.15 x
Since, the sticker price = $ 9,999


Hence, he paid approximately $ 8694.783 for the car.
