640

Step-by-step explanation:

So we want to know how many frogs will there be in 3 months if the frog population doubles every two weeks and there are 10 frogs in the start. So lets see how many weeks are there in 3 months if there is 4 weeks in one month: 3 * 4 weeks = 12 weeks. So every two weeks the population doubles and that means the population will double 6 times in 12 weeks. 20 + 40 + 80 + 160 + 320 640 = 1260 frogs.

Alright so he first week you got 10 frogs so 1=10 and on the second week that number turns into 20 so now its 2=20 now the third week the number stays the same 3=20 and on the fourth week the number doubles again so now its 4=40 so its 40 frogs per month. Now all you do is multiply 40 x 3 and you get 160 frogs. I'm pretty sure this is right if not i'm really sorry.
