1. One of the most commonly used method to measure the distribution of income is the Lorenz curve.
2. Developed in 1906 by Max Lorenz, the Lorenz curve is a graphical representation of the distribution of wealth, or of income.
3. To construct the Lorenz curve, first, people in society or the households are sorted from the lowest income group to the highest.
4. Then, the total portion received from the total income by a number of a group at an arbitrary income level or lower is calculated.
5. If this process is repeated for each income level, the graph of the curve can be constructed, the function y = L(x) which is referred to this curve is called the Lorenz Function.

Which of the statements above related to the Lorentz curve are correct?

If the marginal profit (in millions of TL per year) is given by,
P'(t)=6t²-t+4, find the total profit earned over the first 4 years.

Which of the following features about Lorenz function is false?

1. The notions of indefinite and definite integrals both of which have widespread applications in economics.
2. In marginal analysis, the quantities are differentiated to obtain the rate of their changes.
3. Using the integral we may acquire the totality of the functions such as cost, revenue, profit and so on.
4. Integration may be used to calculate the total income during a given period from a continuous income stream, the consumer and producer surplus, and present and future values of a continuous stream of payments, to name but a few.

Which of the statements above related to the applications of integral in economics are correct?

The management of a national change of market outlets is selling a 10 year franchise in Turkey. Past experience in similar localities suggest that t years from now the franchise will be generating profit at the rate of f (t) = 18000 TL per year. If the prevailing annual interest rate remains fixed at 10% compounded continuously, what is the present value of the franchise?
