Answer:

42 teaspoons of vinegar should be used

Explanation:

This question is solved by proportions, using a rule of three.

4 teaspoons of vegetable oil and 12 teaspoons of vinegar. 14 teaspoons of vegetable oil were used

So

4 teaspoons of vegetable oil - 12 teaspoons of vinegar

14 teaspoons of vegetable oil - x teaspoons of vinegar

So


4x = 12*14

Dividing both sides by 4:


x = 3*14 = 42

42 teaspoons of vinegar should be used
