XYZ Company is setting up a maintenance schedule for a major piece of equipment. Allow the user to enter the cost and the purchase date. They must perform basic cleaning in $10$ days, tube and fluid checks in $3$ weeks, and a major inspection in $6$ months. Determine each date in the maintenance schedule. Determine the monthly amortization for theequipment based on a useful life of $15$ years $(180$ months$)$ and a salvage value based on $10\%$ of the purchase cost. The formula to calculate the monthly amortization is amortization $=($Cost $$Salvage value$)/$ Number of months.
