A new machine was added to increase the capacity of a workshop. The machine cost $$105,000$ and has an estimated service life of six years. At that time, the estimated salvage value would be $$6,000.$ The machine is expected to operate $3,500$ hours per year. The expected annual operating and maintenance cost would be $$10,000.$ If your firm's interest rate is $10\%,$ what would be the machine cost $($owning and operating$)$ per hour?

The machine cost per hour would be $$9\mathrm{.}52$
