Let 
be the number of days spent at Tahoe and San Francisco, respectively.
We don't know the values of 
and 
yet, but we know that the holiday lasted 9 days:
We also know that each day spent in Tahoe costed 350 and each day spent in San Francisco costed 475. So, the total cost of the holiday is the sum of the number of days muliplied by their cost:
If we put the two equations together, we have the system
Which yields
Possibly $16.89 because you multiply 55.08 and .08 to find 4.41 then you subtract that to 55.08 to find the total cost without tax which is 50.67. Then you divide by 3 because there are 3 girls to 16.89.
