It costs Php 100.00 per meter to run the power lines on the land and Php 150.00 per meter to run underwater. Write the cost C of running the line from the power station to the factory as a function of x.

you don't say what x is
I assume it is the distance (in meters) from the factory to where the pipeline comes ashore. If so, then
C(x) = 100x + 150√((5000-x)^2 + 500^2)
