Unit 7 • Lesson 10.8h

Unit Launch: Sarah's Inventory Problem

To launch Unit 07 with a clear founder problem: Sarah can feel the pressure of buying, selling, pricing, and tracking inventory across a month, but she cannot yet defend the ending inventory number with confidence.

What You'll Learn
  • Describe the business problem Sarah faces when inventory purchases and sales pile up across one month
  • Use the ending inventory equation as the scoreboard for the number Sarah must eventually defend
  • Observe that buying inventory, selling inventory, and ending the month with inventory on the shelf create different business effects
  • Launch a shared business simulation that will carry through the rest of Unit 07
Key Concepts
Ending inventory is a number the business must be able to explain
The unit formula is the scoreboard for Sarah's month: Beginning Inventory + Purchases - Cost of Goods Sold = Ending Inventory
Buying inventory, selling inventory, and holding inventory are not the same thing
