Please this is due in 30 minutes. sorry for the rush :(

In the following diagram,Srepresents the position of a power relay station located on a straight coastal highway, andMshows the location of a marine biology experimental station on an island. A cable is to be laid connecting the relay station with the experimental station. The cost of running the cable on land is$4/running foot and the cost of running cable under water is$7/running foot.

Find an expression in terms ofxthat gives the total cost of laying the cable.

c(x) = answer here please

What is the total cost whenx=2250? Whenx=3250? (Round your answers to the nearest cent.)

x=2250 = $(answer here please)

x=3250 = $(answer here please
