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 que...

For me to solve the system of equations for the total cost of lawn care using the tequnique substitution am I right to say: c=$200+$50h c=$300+$25h would be c=$250 c=$325
