One algebra problem please?
The cost C of steel tubing varies jointly as it;s length L, in feet, and diameter D, in inches. If a 3 foot tube with a 4 inch diameter costs $60, find the cost of a 5 foot tube with a diameter of 10 inches. What is the cost of a 5 foot tube with a diameter of 10 inches? $

$60(5/3)(10/4) = $250
