We assume that the ticket price per person is one yuan (a > 0), and there are m women among 40 people (0≤m≤40).

So there are 40 million people.

If all the group tickets are purchased, the total price required is 40a×80%=32a.

If women enjoy women's day discounts instead of group tickets, the total price required is:

(40m) Ampere+mA * 50% = (40m) Ampere+0.5mA = (40-0.5m) Ampere

① If 32a=(40-0.5m)a

= = = & GT32 = 40-0.5m.

= = = & gt0.5m=8

= = = & gtm= 16

That is, when the number of female employees is 16, the total price of the two preferential ways is the same;

② If 32a < (40-0.5m) a

= = = & GT32 < 40-0.5m.

= = = & gt0.5m
