6. Marko wants to go on a winter vacation in January. He started saving in September and saved 387 kn. In October, he saved $269 \mathrm{kn}$ more than in September, and in November, he saved 55 kuna less than the total of the first two months. December brought Marko a third of the total savings from the first three months. Does Marko have enough for the winter vacation, if the cost of the vacation is $2950 \mathrm{kn}$?
In October, he saved $387 \mathrm{kn} + 269 \mathrm{kn} = 656 \mathrm{kn}$. ..... 1 point
In November, he saved ( $387 \mathrm{kn} + 656 \mathrm{kn}) - 55 \mathrm{kn} = 988 \mathrm{kn}$. ..... 2 points
In December, he saved ( $387 \mathrm{kn} + 656 \mathrm{kn} + 988 \mathrm{kn}$ ) : $3 = 2031 \mathrm{kn} : 3 = 677 \mathrm{kn}$. ..... 3 points
In total, he saved $387 \mathrm{kn} + 656 \mathrm{kn} + 988 \mathrm{kn} + 677 \mathrm{kn} = 2708 \mathrm{kn}$. ..... 2 points
$2708 < 2950$, Marko does not have enough money for the winter vacation. ..... 2 points
