Calculate Tax/Sales:
Machinery: \( \frac{5,001}{67,005} \approx 0.0746 \)
Electricity: \( \frac{2,394}{82,308} \approx 0.029 \)
Diversified: \( \frac{2,394}{128,125} \approx 0.0187 \)
Food: \( \frac{7,467}{98,476} \approx 0.0758 \) Order: Diversified<Electricity<Machinery<Food So rank 3 goes to: Diversified
