In order to attract citizens to visit Putuo Mountain Scenic Area, Zhangjiagang Yongan Travel Agency has introduced the following charging standards: (1) There is a team of 35 people.

(1) per capita travel expenses = 1000-(35-25)×20=800,

So the answer is 800;

(2) Suppose that X employees of this unit travel to Putuo Mountain Scenic Area this time.

∵27000>25× 1000,

∴x>25；

∴[ 1000-20(x-25)]x=27000，

Solution: x 1=45, x2=30,

∫ 1000-20(x-25)≥700

∴x 1=45 (not in line with the meaning of the question, omitted), x2 = 30.

A: This time, 30 employees of our unit traveled to Putuo Mountain Scenic Area.
