Answer:

$92,250 per town

Step-by-step explanation:

See attached image.

The two towns may be connected with a straight line, the road, that can be made into the hypotenuse of a right triangle.  The twio sides are calculated from the coordinates and shown in the image.  Then use the phythagorean theorem to calculate the hypotenuse.  The towns are 12.3 km apart.  The total road cost would be:

 ($150,000/km)(12.3 km) = $1,845,000, or $92,250 per town.
