Rank suppliers with published weights

A sourcing team has already scored three suppliers on the same 0–100 scale. Apply the agreed weights and explain why the highest price score does not win overall.

SOURCE DATA
"supplier","price_score","quality_score","delivery_score"
"A","80","90","60"
"B","70","85","90"
"C","95","60","70"

RULES
Higher scores are better in every column, including price_score. These are scores, not quoted prices.
Use weights of 40% price, 35% quality and 25% delivery; they sum to 100%.
Calculate before rounding. Report final scores to two decimals. There is no extra eligibility gate in this fixture.

MY FIGURES
Supplier A weighted score: __________
Supplier B weighted score: __________
Supplier C weighted score: __________
Winning margin (points): __________

MY REVIEW NOTE
________________________

METHOD
A scores 80 × .40 + 90 × .35 + 60 × .25 = 78.50.
B scores 70 × .40 + 85 × .35 + 90 × .25 = 80.25; C scores 76.50.
Rank B first, A second and C third. B’s stronger delivery score offsets its lower price score under these particular weights.

REFERENCE ANSWERS — try first
Supplier A weighted score: 78.5. 32 + 31.5 + 15 = 78.5.
Supplier B weighted score: 80.25. 28 + 29.75 + 22.5 = 80.25.
Supplier C weighted score: 76.5. 38 + 21 + 17.5 = 76.50.
Winning margin (points): 1.75. 80.25 − 78.50 = 1.75 points.

Averaging the three columns equally silently changes the agreed decision rule. Also avoid treating a high price score as a high cash price.

Retain the score definitions and weights with the decision. A sensitivity check can show whether modest weight changes alter the ranking; this score alone does not establish supplier reliability.
