The floor, and how close you came to it.
You are deciding whether to raise the reorder level on a fast-moving part. Put the lowest stock level of the week in B7.
Solve it on your own to keep the bonus. Each hint gets one step closer to the formula.
The same formula in the other shapes it takes at work.
This is the grid you start with. Cell references in the task — B6, C2 — point at the row numbers and column letters below.
| A | B | |
|---|---|---|
| 1 | Day | Stock at close |
| 2 | Monday | 142 |
| 3 | Tuesday | 96 |
| 4 | Wednesday | 31 |
| 5 | Thursday | 88 |
| 6 | Friday | 117 |
| 7 | Lowest point |
The week averaged 94.8 units in stock, which sounds perfectly comfortable. On Wednesday there were 31. The average hides the moment it nearly went wrong, and a reorder level has to be set against that moment rather than against the typical day.
