Looking at each criterion:

C1: PASS - The answer states 429.
C2: PASS - Shows 240 + 185 + 310 = 735.
C3: FAIL - Computes 40% of 441 instead of 735.
C4: PASS - The refused shipment is explicitly ignored.
C5: PASS - Salary never appears in the arithmetic.
SUMMARY: Right answer, but the Tuesday step was reasoned incorrectly.
