The following describes loans for the purchase of cars:
1. A person has a name, an address and an age. A person may be

working for one or more, but for no more than three companies. A
person receives a salary from each company he/she works for.

2. The disposable income of a person is the sum of all salaries received
divided by the persons age and then decremented by a tenth of the
sum of the prices of all the cars owned by this person, and a fifth of
the remaining amount on each of their existing loans.

3. A car has a number plate, a horsepower, and a mileage. A car may be
owned by a person, a company or a bank. The price of a car is its
horsepower multiplied by 10000 and then divided by the mileage.

4. A company has a name, an address, and a turnover (i.e. money
received before paying the employees).

5. The disposable income of a company is calculated as its turnover,
decremented by the salaries of all employees, and a fifth of the
remaining amount on each of their existing loans.

6. A bank has a name, an address and an interest rate.
7. Companies or people may apply to a bank for a loan to buy a car.
8. The bank grants the loan to a person, if the persons disposable

income exceeds the price of the car multiplied by the interest rate. The
bank grants the loan to a company if the companys disposable income
exceeds the price of the car multiplied by the interest rate.

9. When a person or company receives the grant of a loan, then he/she/it
sends back a letter of acceptance.
