    Answer:

    42 teaspoons of vinegar should be used

    Step-by-step 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
