How many values of r are there such that $\lfloor r \rfloor + r = 15.5 + \lfloor r/4 \rfloor?$

There is no value of r that makes this true

 

See the graph here (in  x)  of  the function   :     floor (r)  + r  - 15.5 - floor (r/4)

If we set this function to 0,  the graph never intercepts the  x  axis

 

So....no solution
