Answer:

The equation of demand function is

y=-\frac{1}{2000}x+29

Step-by-step explanation:

We have two point demand function

(38000,10) and (42000,8)

Here x_1=38,000, y_1=10, x_2=42000, y_2=8

The slope of the demand function line is

=\frac{y_2-y_1}{x_2-x_1}

=\frac{8-10}{42000-38000}

=\frac{-2}{4000}

=-\frac{1}{2000}

The equation of demand function is

y-y_1=m(x-x_1)

\Rightarrow (y-10)=-\frac{1}{2000}(x-38000)

\Rightarrow y-10=-\frac{1}{2000}x+\frac{38000}{2000}

\Rightarrow y=-\frac{1}{2000}x+19+10

\Rightarrow y=-\frac{1}{2000}x+29

Answer:

B. 236.3

Step-by-step explanation:

Population density can be found by dividing the number of people by the area of the land.

number of people / land area

The population is 20,510 people and the area is 86.8 square miles.

20,510 people / 86.8 square miles

Divide 20,510 by 86.8

236.290323 people /square mile

Round to the nearest tenth. The 9 in the hundredth place tell us to round the 2 to a 3 in the tenth place.

236.3 people/ square mile

There are 236.3 people per square mile and B is correct.
