Every Number Has a Job
You'll learnto build an actual model by giving every number in the story exactly one job.
Choosing the family is one job; writing the actual function is another. That means naming the quantities and their units before touching a number, then giving every number in the story exactly one slot. Read the finished model back and each parameter should say something about the situation. Eleven short steps; press Next for each one.
one slot per number · units travel with it
