Refactor — Bind the Range Once with LET

A finance analyst's "regional high-value revenue" formula repeats the same long range twice in every cell. Their original was:

=SUMIFS($C$2:$C$17, $B$2:$B$17, E2, $C$2:$C$17, ">5000")

The revenue range $C$2:$C$17 appears once for the sum and again as a criteria range (because the threshold filter is on revenue itself). When the source data grows from 16 rows to 16,000, both occurrences need to be updated — and forgetting one is the #1 way these formulas drift wrong.

LET solves this: bind the range to a name once, then reference the name. Refactor target:

=LET(
  rev, $C$2:$C$17,
  reg, $B$2:$B$17,
  target, E2,
  SUMIFS(rev, reg, target, rev, ">5000")
)

Same answer, but the range is now defined in one place. Three regions are pre-populated in column E.

Your task:

1. In column F (High-Value Total), write a LET-based formula that returns each region's total revenue from rows where revenue is greater than $5,000.
2. The formula must drag-fill from F2 → F4. The grader checks the values, not the LET usage — so the original SUMIFS form also passes — but the style point is to practice LET.

Graded cells: F2, F3, F4.
