How much should I charge for 33 days of house sitting?

I'm not sure how much to charge per day

I'm going to be House sitting(staying at the owner's house) for around 14-33 days.

I'll be provided with food and boarding.

I'm going to take care of an elderly dog, they don't go on walks but rather go out into the yard, and I can leave them at most for 7 hours a day to commute to go to work, which driving back and forth would be 2 hours of driving.

how much would you charge?
