Position 1

In order to sell their products easily, the founding members of the cooperative want to buy a used car worth 5,000,000 CFA francs. They have decided to make monthly payments. At the end of the first month, they must collect the same 500,000 CFA francs. Before the start of the competition, two new members have registered.
