Counting a range of cells that include text and numbers

Hey guys,

So I have been scouring the site looking for help with a particular single-cell formula to count a range of cells that have both text and numbers. Easiest way to explain is with an example:

SalesID 10
SalesID 13
SalesID 17
SalesID 21
SalesID 28
SalesID 31
SalesID 32
SalesID 33
SalesID 37
SalesID 38
SalesID 43
SalesID 53

What would be the right formula to find the number of SalesID's in the 30-40 range without separating the numbers from the text into a separate column?

Thanks in advance for the help!
