Answer:
If your bottle already has 550 ml in it you need to add 1,700 ml for a total of 2250 ml. If your bottle can only hold 550 ml you will need to drink about 4 bottles in order to drink 2250 ml of water.

Hi 
First we must how much she has to spend to do all the miles. 
as each mile is  0.15 she needs   0.15 * 375 = 56.25  dollars.  
Now the compagny charges 69.72 for each day.  Let's call X numbers of days. 
Then we have to solve :  
69.72 X + 56.25  = 470
69.72 X = 470 -56.25 
 69.72 X = 413.75 
            X =  413.75 / 69.72 
            X = 5.93 ...  
As the compagny charges whole days, she can keep it only 5 days.
