某工程，业主在招标文件中规定：工期T(周)不得超过80周，也不应短于60周。某施正单位决定参与该工程的投标。在基本确定了技术方案后，为提高竞争能力，对其中某技术措施拟定了3个方案进行比选。方案一的费用为C1＝100+4T；方案二的费用为 C2＝150+3T；方案二的费用为C3＝250+2T。

这种技术措施的3个比选方案对施工网络计划的关键线路均没有影响。各关键工作可压缩的时间及相应增加的费用见表6-1。

假定所有关键工作压缩后不改变关键线路。

若招标文件规定，施工单位自报工期小于80周时，工期每提前1周，其总报价降低2万元作为经评审的报价，则施工单位的自报工期应为多少经评审的相应报价为多少？
