    Given:

    must correctly answer 80% of the questions

    correctly answered questions = 26

    incorrectly answered questions = 4

    unanswered questions = 15

    Total questions = 26 + 4 + 15 = 45

    45 * 80% = 36 required correctly answered questions.

    36 - 26 = 10

    Out of 15 remaining questions, 10 questions must be correctly answered for Heidi to advance to the next level.
