What should I get payed for the following chores?

Considering your room and board are paid for, then I would give them a Family Discount. If you worked about 12 hours, I would consider about $5.00-$8.00 an hour...... so perhaps you could ask for a flat $100.00. Be sure to ask if it's fair. If it's too high, then go to $75.00. See what they're comfortable with.
