The numbers are in.

2= the number of students I've made cry since the first day of school
35= the number of school-owned harps in this county (I think of it as me suddenly adopting 35 children)
.0004= number of harps per capita in Odessa
1362= the collective number of strings on the harps in Odessa
1099= number of harp strings tuned per school day
486= the number of harp strings I've changed since the first day of school
62= the number of days that it's taken me to change strings and make sure every harp is in tune and in playable condition
.05= number of chihuahuas per capita within the city limits of Odessa (estimate)
97= percentage of chihuahuas in Odessa that are stray
92= percentage of stray chihuahuas I see during the course of the school day
.008/1= harp-to-chihuahua ratio in Odessa

Now, if we plug those numbers into this equation:

5d+3a-2(3[25])-psum-i-(d+t)= profit

Our profit turns out to be:

.06
