What is the number of real solutions?
–11x2 = x + 11

cannot be determined
one solution
two solutions
no real solutions

Initial price of car = $x

After one year the price of car = $0.88x

to find the change in price we subtract the price after one year from initial price.

It means change in price = (x-0.88x)= 0.12x

By this we can easily see that , price dropped by 0.12

Or we can say that price dropped by 12%

So option C is the correct answer

C) 12% decrease
