Samuel charged me d dollars to fix my broken heater. He
also charged me $65 for parts. He worked for 3-hours
and my total charge was $110. How much did he charge
me per hour?
Since he charged $65 for the parts, and the total charge was $110, that's $110-$65 which is $45, the total hours was 3, so $45 divided by 3, and that equals $15.
