Find the optimum replacement interval AND the minimum EUAC for each of the scenarios below.

Please show cash flow diagram and do not use excel functions.

$225,000 is invested in equipment having a salvage value that decreases by 25% per year. O&M costs equal $45,000 the first year and increase by $30,000 per year. Consider a MARR of 10%.
