Case 1: Annual cash flows does not include other cash flows
=(60000-(113000+13000)*15%)*(1-35%)+(113000+13000)*15%=45615
Case 2: Annual cash flows includes other cash flows
=(60000-(113000+13000)*15%)*(1-35%)+(113000+13000)*15%+7500+62150-(62150-(113000+13000)*7%)*35%=96599.50

NPV=-(113000+13000+7500)+((60000-(113000+13000)*33%)*(1-35%)+(113000+13000)*33%)/1.08+((60000-(113000+13000)*45%)*(1-35%)+(113000+13000)*45%)/1.08^2+((60000-(113000+13000)*15%)*(1-35%)+(113000+13000)*15%+7500+62150-(62150-(113000+13000)*7%)*35%)/1.08^3=43220.0115581974
