86.83$

Step-by-step explanation:

15% of 75.50 is 11.325

so then  you add that back to 75.50 to get 86.825 if your round that you get 86.83

Every 5 minutes the amount of bacteria would double. So five minutes would allow for the bacteria to fill one bottle since you already have one filled then the next five minutes it doubled again and since u have two bottles doubling two would mean you filled the last two bottles
