Answer:
5
Step-by-step explanation:
10-(2+3) = 5
Step-by-step explanation:
Given
x² - 9x + 20 = 0
x² - ( 4 + 5) x + 20 = 0
x² - 4x - 5x + 20 = 0
x ( x - 4 ) - 5 (x - 4 ) = 0
(x - 4 ) ( x - 5 ) = 0
Either
x - 4 =0
x = 4
or
x - 5 =0
x = 5
x = 4 and 5

You should probably define what makes a car "nice", and also quantify the "too much money".
Qualitative words are often not welcomed in maths/science in general, because people can disagree on their meaning.
So, for example, if you change the sentence into
"A report states that 32% of New Jersey residents think that mercedes cars cost 30% more than they should"
Then everything would be "fixed", and there is no ambiguity anymore
