Oof actually IDK the answer. I can't figure it out. I got the answer 1,344 but I'm sure that's not right. I'm so sorry! :(
About 20 cars. Easiest way to figure it out is do 231$ divides by 12$ and get 19.25, so 20.
Minus 16x both sides and add 28 to both sides
x^2-16x+28=0
factor
hmm, what 2 numbers multiply to 28 and add to -16
hmm
1 and 28? nope
2 and 14? yep
since middle term is negative and last tem is positive, both of the factors are negative
(x-14)(x-2)=0
set each to zero
x-14=0
x=14
x-2=0
x=2
x=2 and 14

Write the parent function in the standard form I.e.

Where,
