14) A power line is to be installed across a river that is 1 mile wide to a town that is 5 miles downstream from the power source on the other side of the river. (See diagram below.) It costs $7000 per mile to lay the cable underground and $9000 per mile to lay it underwater. Determine the distance in miles x the cable should run underground along the river from the power source and then be run underwater diagonally to the town if a total of $45,000 has been allocated and will be totally used for this project. (Show all work to justify your answer(s) for x and round your final answer(s) to two digits behind the decimal point and remember 0 5 x 5 5 miles. This is a lengthy problem so you can finish it on the next page.)
