Textbook Problem

In Problems 15-24, p is the price per unit in dollars and q is the number of units.

If the weekly demand function is p   = 30  -  q and the supply function before taxation is p =   6   + 2 q , what tax per item will maximize the total tax revenue?

To determine

To calculate: The tax per item that will maximize the total tax revenue if the demand function for a fixed period of time is given by p=30q and the supply function before taxation is p=6+2q.

Explanation

Given Information:

The provided expression is the demand function for a fixed period of time is given by p=30q and the supply function before taxation is p=6+2q.

Formula Used:

The following procedure are used to maximizing total tax revenue,

Step-1 Write the supply function after taxation,

Step-2 Equate the demand function and new supply function to get number of units and tax.

Step-3 Calculate the total revue function T that will be product of number of units and tax.

Step-4 Calculate the derivative of revenue function and set equal to zero and solve.

Step-5 Calculate second derivative test to verify the result.

Calculation:

The provided expression is p=6+2q,

After the taxation, the supply function is equal to p=6+2q+t. The demand function will meet the new supply function is:

Put the new supply (after taxation) equal to the demand.

6+2q+t=30q

Solve to equation further to get the value of t,

Add 30+q on both the sides,

6+2q+t+(30+q)=30q+(30+q)6+2q+t+(30+q)=0

Deduct t from both the sides,

6+2q+t+(30+q)t=0t

Multiply by -1 on both the sides,

243q=t

Then, compute the total tax by the formula T=tq,

T=q(243q)=(24q3q2)

Tax is maximized as follows:

The first derivative of T is as follows:
