P1.2-d: Solve using Exponential function to find the duration at which the annual cost of maintenance is double the initial year for new compressor. The yearly cost of maintenance of two compressors is $500 for each in the initial year. Due to excessive usage the cost of maintenance increases after initial year as follow: A. For the old compressor by 6%. B. For the new compressor by 3%. The recommended compressor should be selected in regards to best value of maintenance cost P1.2-d: Solve using Exponential function to find the duration at which the annual cost of maintenance is double the initial year for new compressor.
