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.

A train travels between two stations 1/2 mile apart in a minimum time of 41 sec. If the train accelerates and decelerates at 8 f
igomit [66]
It is important to notice firs of all that the train with no stop acceleration and them no stop acceleration would have a faster travel between stops. given this is safe to assume that there is a period during while the train is not accelerating nor decelerating. To find the time that is speed is constant
let's assume non-stop accelerating and decelerating and the time lost (subtraction of both) is the time the train had constant speed:

assuming same time accelerating a decelerating we have that the distance is

x = voT + 1/2aT^2 (initiial speed = 0) (0.25 miles = 1320 feets)
1320 = 1/2 (8)(T/2)^2
T/2 = 18.17 seg
 T = 36.34 seg
time of constant speed 
T = 41 -36.34 = 4.66 seg

maximum speed 

v = v0 + aT (initial speed = 0)
v = 8(18.17)  (time accelerating)
v = 145.36 feets/sec

distance at full speed

x = v*t
x = 145.36*4.66 = 677.38 feets

Assume that the short-run cost and demand data given in the tables below confront a monopolistic competitor selling a given prod
Damm [24]

Given the information stated above, the firms maximum total profit will be $90. (Option A) See the explanation below.

<h3>What is Maximum Total Profit?</h3>

Maximum total profit is the highest profit

<h3>What is the calculation supporting the above answer?</h3>

It is to be noted that the attached excel spread sheet was computed using the following formulas:

MC(n) = TC(n) - TC(n-1)

MC(n) = marginal cost of nth unit

TC(n) = Total cost of n units of output

MC(1) = 40-25=15 and so on

Recall that

Total Revenue (TR) = Price * Quantity

that is:

TR = P * Q

Marginal Revenue of the nth unit of output  =

TR of the n unit of output - TR of the n-1 units of output.

MR(n)=TR(n)-TR(n-1)

MR(1)=55-0=55 and so on

Recall that Profit = TR  - TC

Thus,

Profit (0) = 0 - 25

= -25 and so on

By observation on the sheet, the maximum profit (that is highest profit attainable) is given as $90.

This corresponds with

  • the Quantity of 4 Unit
  • The Marginal Revenue of 25; and
  • Marginal Cost of 15.

Hence, option A is correct.
