x = -52

Step-by-step explanation:

Let's solve your equation step-by-step:

hoa [83]

Answer:

The appropriate answer is "$12".

Step-by-step explanation:

As per the question,

Price per ticket,

= $4+k$

Number of people,

= $1800-90k$

Now,

The revenue (R) will be:

= $Price \ per \ ticket\times Number \ of \ people$

By putting the values, we get

= $(4+k) (1800-9k)$

= $-90k^2+1440k+7200$

or,

⇒ $R'=1440-180k=0$

⇒ $180k=1440$

⇒ $k=\frac{1440}{180}$

$=8$

hence,

The ticket price will be:

= $4+k$

= $4+8$

= $12$ ($)
