Because if you reduce by find their common factors you can see that 2,3 is the same at 4,6. 2,3 times 2 gives you 4,6. Hence forth they are the same line

Situation:
Rzqust [24]
N=NOe^-kt
N=mass at time t
NO = initial mass
k= 0.1476
t= time, in days

We are asked to find the half-life, which means you want to find how long it will take for half of the substance to decay/disappear (depending on situation). 

If we are looking for half-life, we can simply set N to half of NO (which we are given a value of 40grams for)
Therefore:
N = 20
NO = 40
plugging these values and the value given for k back into the equation you get:

20 = 40e^-0.1476(t)
We are looking for t, so we have to manipulate the formula to get t by itself on one side of the equation.
We can start by dividing 40 from both sides, and you get:
0.5 = e^-0.1476(t)

We have the exponential function "e".
To get rid of e, we can use natural log (ln)
if e^y=x then ln (x) = y
look back at our equation we can set
0.5 = x
-0.1476(t) = y

Rewriting it in natural log form:
ln (0.5) = -0.1476(t)
Plug in ln (0.5) on a calculator to find its value and we get:
-0.693147 = -0.1476(t)
*Note: normally, getting a negative value would suggest that we did something wrong, because you cannot have a negative value as your t (you cannot have negative days), but because there is a negative on both sides of the equation, they will cancel out in this case. 

The last step is to simply divide both sides by -0.1476
therefore:
T = 4.696119
But it asks you for the answer to the nearest tenth (one place after decimal pt) so 
T (half life) = 4.7 days

Hope that helps :)

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.
