Question

An average female mouse can give birth to 12 babies once a month. Baby mice can mature and give birth to babies at two months old.

If you bought one of these cute baby mice home from the pet store the day after it is born, how many mice would you have 10 months from now?

Can you solve this one for me? Remember that it's gonna be sooo much.

Answer 1

1st Month: none

2nd Month: none

3rd Month: 12

4th Month 12

5th Month: 12 + 12*12 (from 3rd month) = 156

6th Month: 12 + 12*12 + 12*12 (from 4th month) = 300

7th Month: 12 + 12*12 + 12*12 + 12*(12+12*12) from 5th month = 2172

8th Month: 12 + 12*12 + 12*12 + 12*(12+12*12) + 12(12 + 12*12 + 12*12) from 6th month = 5772

9th Month: 12 + 12*12 + 12*12 + 12*(12+12*12) + 12(12 + 12*12 + 12*12) + 12*[12 + 12*12 + 12*12 + 12*(12+12*12)] from 7th month = 31836

10th Month: 12 + 12*12 + 12*12 + 12*(12+12*12) + 12(12 + 12*12 + 12*12) + 12*[12 + 12*12 + 12*12 + 12*(12+12*12)]  + 12*[12 + 12*12 + 12*12 + 12*(12+12*12) + 12(12 + 12*12 + 12*12)] from 8th month = 101100

Now add each month's numbers together and you get: 141,514

Basically, you have to consider the babies that were born that are also two months old.  They have babies as well.

Answer 2

96??

Answer 3

Is this a riddle?

"If you bought one of these cute baby mice home from the pet store the day after it is born..."

You will only have one mouse in ten months. You only bought one mouse. There's no way for it to be pregnant either since it's only a day old. I'm just following the question exactly how it's written, and it says "if you bought ONE of these cute baby mice."

Answer 4

*hint* you need a male mouse to make baby mice :D
