That sentence is confusing...

That sentence is confusing...
There is no logical relationship between the prepositions.
You can put any angle and its cosine there.
You can put, for example:

Cos(90)=0 or Cos(0)=1... Both are correct options...

If your teacher wrote that, he doesn't know to write very good...

Good luck!

Just divide 1,300 by 5.

260 would be your answer. If you want an explanation, if you think about the term 100%, that's the total at the time. Amplifying that 100% by five would practically mean five times the amount of 100%, so 500%. You're just multiplying the amount of bunnies at the time by 5. (500% in decimal form is 5)
