Phase 5: Capstone · ~60 minutes · Python
Solve It, Then Code It
The code isn't there to find the answer. It's there to catch you if the hand-solved answer was wrong — which is exactly why it has to come second, not first.
Hiring signal: Solves a real quantitative problem by hand first, then uses code specifically to verify — not as a substitute for understanding what the numbers mean
What you will learn
- Solve a translated growth/decay equation by hand, including using logarithms where needed
- Implement the same model in Python and confirm it matches the hand-solved answer exactly
- Apply this course's distance and rate-of-change ideas to compare two modeled scenarios
- Extend a working model with one real-world twist and explain what specifically got harder

What you're building
Your finished capstone, in one folder:
translation.md from Lesson 01, finalizedcapstone_model.py — hand-solved answers shown as comments, followed by the Python model that verifies each one, including the distance comparison and the rate-of-change comparisonstretch_model.py — the changing-rate version, plus your written answer to the Stretch Challenge's question about what had to change- A final paragraph (in
translation.md or a new reflection.md) answering the Ship Prompt: the one math idea from this course that finally made sense in a way it never had before, and why
