Every time Joãozinho goes to the cinema, he drinks two soft drinks. He spent all his allowance of R$ 50.00 going to the cinema six times and drinking a total of 20 soft drinks, including those he drank when he went to the cinema. If Joãozinho had only one soft drink each time he went to the cinema, with this savings he could have gone to the cinema one more time, also drinking one soft drink on that occasion. Regarding the price of the cinema ticket and the price of the soft drink, we can state that

(a) the price of the ticket is three times the price of the soft drink;

(b) the price of the ticket is four times the price of the soft drink;

(c) the price of the ticket is five times the price of the soft drink;

(d) the ticket is R$ 6.00 more expensive than the soft drink;

(e) the ticket is R$ 5.00 more expensive than the soft drink.
The correct option is (c).

The economy would have been equivalent to six sodas, allowing Joãozinho one more movie and one more soda. Therefore, the movie ticket is five times the value of the soda.
