Partial Business Expenses, Internet

Hello, 

 

This year I have started my own LLC and recently acquired a business line of credit. I am trying to do everything correctly and putting the clear business expenses on the card. 

 

In reading these forums, I've read about the itemized version of business expenses and determined that my home internet service would partially meet this requirement, three days of the week when I use it for business. My questions related to this are these:

 

1. If my Internet costs are $100/month and the use of the service for business is 3 days of the week, my figure for that would be 42.86 per month as a business expense Is that correct?

 

2. Should I pay for the internet with my business credit card or continue to pay for it with my personal card, knowing that only a portion of the expense is business related? If I do not pay it with my business card, what's the easiest way to show that reimbursement from my business to myself. 

 

I am the sole member of the LLC, for reference. 

 

Thanks for your assistance in advance.
