Let's start with the first two weeks. We know that 7 days are in a week, so we must multiply 2 and 7. That gives us with 14.
Now we must multiply 8 and 14 because Rosalie collected 8 stickers every day, and there are 14 days. That leaves us with 112.
Now for the 2nd two weeks. We'll start the same and convert weeks into days. After so, we must multiply 14 and 5 because she collected 5 stickers every day. That leaves us with 70.
At last, all we have to do is add our two numbers, 70 and 112. The adds up to 182.
