Output from a process contains $0\mathrm{.}04$ defective unit. Defective units that go undetected into final assemblies cost $$22$ each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who can test $19$ units per hour, is paid $$9$ per hour, including fringe benefits.

Assume that the line will operate at the same rate $($i$.$e$.,$ the current production rate$)$ regardless of whether or not the inspection operation is added.

If the inspection operation is added, what would be the cost to inspect each unit?

Note: Round your answer to $2$ decimal places!!

What would be the benefit $($or loss$)$ from establishing the inspection process?

Note: Input the amount as a positive value. Round your answer to $2$ decimal places!
