Marinada '23

[lang=hr] Opće je poznato da na svijetu postoji $103$ automobila. $39$ ih ima mirisne boriće, a $32$ privjesak kockicu. Automobile koji nemaju ni boriće ni kockicu voze Slavice i samo Slavice, a Slavica je $45$. Jedine Slavice koje ne voze automobile su one koje idu u frizera nedjeljom, a njih je točno ovoliko: "Zamislite jedan broj. Oduzmite mu broj $7$. Dodajte broj $22$. Pomnožite sve sa $3$. Oduzmite tom broju $3$. Konačno, podijelite sve sa $3$ i oduzmite broj koji ste originalno zamislili.". Svaka vozačica Slavica osim Slavice Marić vozi točno jedan automobil. Slavica Marić ih vozi $15$. Koliko automobila ima i boriće i kockicu? [/lang] [lang=en] It is indeed a well know fact that there are $103$ cars in this world. $39$ have pine fresheners, $32$ have a dice. Cars that don't have niether pines nor die are driven only and exclusively by Slavicas and there are $45$ Slavicas. Only Slavicas who don't drive a car are those who go to hairdresser on sunday, and there is exactly this many of them: "Imagine a number. Take away $7$ and add $22$. Multiply by $3$. Now subtract $3$. Finally, divide by $3$ and subtract the number that you've imagined originally." Every driver Slavica, except Slavica Marić, drives exactly one car. Slavica Marić drives $15$. How many cars have both pines and a dice? [/lang]
