did I solve the problem correctly?

c=$200+$50h
c=$300+$25h
is the answer
c=$250
c=$325
Do all I have to do to this equation is to add them to get the total cost of labor with h=labor per hour and c=cost
or do I have to solve it in a different way. I'm sorry for all the questions I know that you are busy and I do appreciat all your help
