I am trying to help my daughter catch up on work after being sick and out of school. So please show steps or explain how to solve. This way I can show her how to solve the other similar problems.

You can put this solution on YOUR website!
hourly wages+commission=income
15*6.25+rate*sales=280.63
rate=r
sales=3250
15*6.25+r*3250=280.63
solve for r
I leave the math for you.
Be careful of decimal points
Make sure the results are reasonable.
He earned only about 90 dollars hourly wages so his commission should be less than $200
So his r should probably be less than 7%
You do the exact calculations.
