2n weeks? Is that how the question is written?

Answer 2

yea

Answer 3

Do you have answer choices?

Answer 4

no

Answer 5

Ohh did you mean to write fortnight or for night?

Answer 6

fortnight

Answer 7

Okay so a fortnight is 14 days which is 2 weeks.
You already have 100 dollars in your account so you would be adding the 30 dollars into your account right?

Answer 8

yes

Answer 9

So far it would look like this:
100 + _____ = S

Answer 10

Since $30 is for 2 weeks what would you do to it to make it for just one week?

Answer 11

half it

Answer 12

right, which is 15. So it would just be $15 for every 2n weeks. I don't know why they put 2n it makes the question really confusing

Answer 13

Did they have any more information for the question or is that all they had?

Answer 14

thar is it thanks :)

Answer 15

Oh okay. You're welcome!
