Purchase of sorting and shrink-wrapping attachment $25,000 Installation of attachment 5,000 Replacement parts for refurbishment of machine 15,000 Labor and overhead related to the refurbishment 9,000

The refurbishment improved machine efficiency by 20%. Neither the attachment nor the refurbishment increased the estimated useful life of the machine. What amount of the above costs should be capitalized?
