Answer:
Step-by-step explanation:
Consider the revenue function given by . We want to find the values of each of the variables such that the gradient( i.e the first partial derivatives of the function) is 0. Then, we have the following (the explicit calculations of both derivatives are omitted).
From the first equation, we get, .If we replace that in the second equation, we get
From where we get that . If we replace that in the first equation, we get
So, the critical point is . We must check that it is a maximum. To do so, we will use the Hessian criteria. To do so, we must calculate the second derivatives and the crossed derivatives and check if the criteria is fulfilled in order for it to be a maximum. We get that
We have the following matrix,
.
Recall that the Hessian criteria says that, for the point to be a maximum, the determinant of the whole matrix should be positive and the element of the matrix that is in the upper left corner should be negative. Note that the determinant of the matrix is and that -10<0. Hence, the criteria is fulfilled and the critical point is a maximum
Answer:
The amount paid monthly will be 161.5 pound
Step-by-step explanation:
It is given that the cost of the car is 6720 pound
It is given that cost of every car is reduced by 20 %
So new cost of car =
It is given that he has deposited 1500 pound
So the amount which he has to deposit = 5376 -1500 = 3876 pound
He paid the left amount in 24 equally
So the monthly paid amount =
