Question 43
An airline does not charge a passenger extra for luggage if the mass of the luggage does not exceed a certain allowed mass. For each additional kilogram of luggage, however, the passenger must pay extra. Mr and Mrs Kotnik have joint luggage, so they would not be charged extra if the mass of the joint luggage did not exceed twice the allowed mass. Their joint luggage weighs $60~\mathrm{kg}$, and they had to pay 11 euros extra. The luggage of Mr Novak, who travels alone, also weighs $60~\mathrm{kg}$. But he had to pay 33 euros extra for his luggage. At most how many kilograms of luggage can one passenger have without having to pay anything extra?
