Answer:
The purchasing department increased operating profits by almost three times the amount that the additional sales generated.
Explanation:
The sale of $30 million in additional products generated $3.6 million in additional operating profits (= $10 million x 12%).
But the savings generated by the purchasing department increased operating profits by $10 million, which is almost three times the amount that the additional sales generated: $10 million vs. $3.6 million.
