解：
每年折旧=1500/5=300
初始现金流量（第一年）=1500
每年净利润以及营业现金流量
年份 2 3 4 5 6
销售收入 500 700 900 1100 1300
付现成本 170 170 170 170 170
折旧 300 300 300 300 300
所得税 7.5 57.5 107.5 157.5 207.5
净利润 22.5 172.5 322.5 472.5 622.5
营业现金流量 322.5 472.5 622.5 772.5 922.5
终结现金流量=0
净现值（NPV)=322.5*PVIF10%,2+472.5*PVIF10%,3+622.5*PVIF10%,4+772.5*PVIF10%,5+922.5*PVIF10%,6-1500
=322.5*0.826+472.5*0.751+622.5*0.683+772.5*0.621+922.5*0.564-1500
=546.4万
回收期
年份 1 2 3 4 5 6
回收额 0 322.5 472.5 622.5 772.5
剩余额 1500 1177.5 705 82.5
所以，回收期为：4+82.5/772.5=4.11年
