Solve the problem.An oil platform is 7 miles off the coast, and a pipeline needs to run to a refinery that is 15 miles north of the platform along the coast. This requires that some of the pipeline will be offshore and some will run on land along the coast. If the pipeline comes on shore x miles north of the platform, the underwater distance is given by f(x) = 
, and the distance on land is given by g(x) = 15 - x. The cost of the underwater pipeline is $500,000 per mile, and the cost of the pipeline on land is $350,000 per mile. If the pipeline comes on shore 6 miles north of the platform, what is the total cost of the pipeline? Do not round until the final step and then round to the
nearest cent. A. $7,759,772.23 B. $7,726,840.56 C. $6,709,772.23 D. $7,287,817.78
