Heidleman Industries is considering two types of materials for roofing its warehouses. EPDM is an elastomeric polymer synthesized from ethylene, propylene, and a small amount of diene monomer, compounded with carbon black processing oils and various cross-linking and stabilizing agents. The 75 mil thickness will cost $5.50 per square foot and will last for 10 years. A thin sheet aluminum (TSA) roof will cost $7.00 per square foot, but it will last for 15 years. Using an interest rate of 10% per year, calculate the annual worth per square foot for the EPDM and TSA roof and which alternative should be selected. EPDM=$0.90 per square foot; TSA =$0.92 per square foot (Select EPDM) EPDM=$0.41 per square foot; TSA=$0.57 per square foot (Select EPDM) EPDM=$0.65 per square foot; TSA=$0.47 per square foot (Select TSA) EPDM=$0.65 per square foot ;TSA=$0.47 per square foot (Select EPDM) EPDM=$0.41 per square foot ;TSA=$0.57 per square foot (Select TSA) EPDM=$0.90 per square foot; TSA=$0.92 per square foot (Select TSA )
