Ellen is paid $35 an hour but gets time and a half on sunday's. how much would she receive if she worked 6 hours on sunday?

You can find this by finding how much she would be paid per hour and then multiplying it by 6. So, you have $35 for the other days but on Sunday's it is that and then half of that added on just in one hour. 
35+(1/2)(35)= 35+17.5=$52.5/hour
after you find this value you need to multiply it by 6 hours in order to be left with $315. 
Now if you can just put a good word in for me at that job :)
