How much should I get paid?

-I'm helping a slightly disabled person around their house. This includes things like doing their laundry, cleaning their house, doing maidwork, etc. PLUS running errands for them such as shopping and such.



What should I request as pay? I have absolutely no clue so I guessed minimum wage per hour and then they pay for gas when I run errands for them. How would I even go about knowing how much they should pay for gas?



Any ideas? I need help asap! I'm leaving in 30 mins to talk to the person about the job.



Thanks!
