Question

A cable is being replaced 15 meters beneath the surface of a body of water. The new cable must extend from a pole located 9 meters above the surface of the water. A contractor can bill $30 for each meter of cable replaced. What is the minimum cost of the replacement?

Explanation:

Total cable length = 15m + 9m = 24m

$30 per meter * 24m = $720
