Question 1
Tax system -
A tax system needs to be updated due to new legislation. For a person with a salary of less than
20.000 and who is married, the tax needs to be re-calculated. If the person also has more than two and less than five children, an additional 10% reduction is applicable.

Question 4
A temperature unit holds the temperature between 10 degrees Celcius and 10 degrees
Celcius. If the temperature drops below 10 or rises above 10 then an alarm rings.
