If you increase the price 9 times which is 5 dollars more each time you get only 30 students that are willing to buy it. Any more increases will lead to no one wanting to buy it.

Answer:

The answer is $35.

Step-by-step explanation:

If you do the process, you will get $35. First, put in the calculator 20 x 300 to get 6000. Now for each time after this, add five dollars to the price of the calculators and subtract 30 students from the total number of students. You will notice that any price after $35 decreases from a revenue of $7,350. So therefore, the answer is $35.

MakcuM [25]

Recall that

\mathcal L_s\{t^ne^{ct}\}=\dfrac{n!}{(s-c)^{n+1}}

Then

F(s)=\dfrac2{(s-5)^3}+\dfrac4{(s-5)^2}+\dfrac7{s-5}
