The alley - Boss 3rd mission

Hi. I can´t complete the 3rd mission of the Boss. Here is what I have to do:
-You must collect a total of $100,000,000 from your hookers
-You must have invested a total of at least $3,000,000,000. You have so far invested $0
I have done the 1st point, but I can't manage to find what I have to do in the 2nd point. I have already tried to buy some hookers, but the money invested doesn't change. Can anyone help me?

Hi, sampaios,

for 2nd point, you must go to bank section, and at the bottom you will find investments
