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.
The disposable income of a person is the sum of all salaries received divided by the person¡¯s 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.
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.
A company has a name, an address, and a turnover (i.e. money received before paying the employees).
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.
A bank has a name, an address and an interest rate.
Companies or people may apply to a bank for a loan to buy a car.
The bank grants the loan to a person, if the person¡¯s disposable income exceeds the price of the car multiplied by the interest rate. The bank grants the loan to a company if the company¡¯s disposable income exceeds the price of the car multiplied by the interest rate.
When a person or company receives the grant of a loan, then he/she/it sends back a letter of acceptance.
