Marco’s Uncle Oscar gave him 2 mice, which he named Whiskers and Oscar. But Marco discovered that he made a big mistake. Oscar should have been named Oscarella. She just had 8 babies — 4 males and 4 females! “Ten mice aren’t so many,” said Marco to his mother. “And they’re cute.” “Yes,” said his mother, “but these cute baby mice can breed when they are 6 weeks old. The babies are born after 3 weeks of pregnancy.” If each female mouse has only 1 litter and all the litters have 8 babies, half males and half females, how many mice will Marco have in 18 weeks? |
