Answer:
The correct answer is option B. Return on Investment.
Step-by-step explanation:
The return on investment is used when we want to measure the capacity of an investment, or compare it among several other investments.
Here the <u>benefit of a certain investment will be compared in contrast to the money invested. </u>
To calculate the return on investment there is a formula which will give us a percentage:
ROI = Margin on sales X asset turnover.
Now let's clarify what each of these things is:
Margin on sales: it is the result obtained from the calculation of benefits / sales.
Asset Rotation: this is the result obtained from the calculation of Average Total Sales / Assets.
R+s-t-(r-s+t)
=2s-t is the answer
People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t
You would assume you would go r-r and thats 0 so no r's
you would say s-(-s) makes it plus and theres 2s
and you would say -t -(+t) is -t
that's why the answer is 2s-t
At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t
Answer:

Step-by-step explanation:

take derivative with respect to t

derivative of e^t is e^t
derivative of 0.23t is 0.23

Apply chain rule
