Your café is suddenly swarming with flies!  You want to know exactly how many there are, but it’s too difficult to count them.  You hang fly traps in the kitchen and customer seating area and return to count the next day.
In the kitchen, there are 49 flies caught on traps, and at least 10 still flying around, but no more than 25.
In the customer seating area, there are 78 flies caught on traps, and at least 20 still flying around, but no more than 50.
Write two different numeric expressions, using “f” to represent the total number of flies in the café, showing the least and greatest amount possible.

What is the range of the total possible number of flies in the café?
