Two machines are being considered to do a certain task in a manufacturing plant. Machine A costs $240,000 new and $26,000 to operate and maintain each year. Machine B costs $320,000 new and $12,000 to operate and maintain each year. The machines are identical in all other aspects and will have no salvage value after eight (8) years. Assume an annual effective interest rate of 7.0%. Determine (by the equivalent uniform annual cost method) which alternative is least expensive.
