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:

Hope you can see my workout in the picture I attached below.
f⁻¹(x) =

AND
f⁻¹(19) =
It's b. You have to times $4 by 6 to get $24. Then you take it away from $30 to get the change so $6
