    Answer:Julie's average score was 76

    Step-by-step explanation:

    The formula for Average or mean is expressed as

    Average = sum of terms / total number of terms.

    Julie's first three test scores in biology were 65, 90 and 73.

    The sum of the scores would be

    65 + 90 + 73 = 228

    The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,

    Average = 228/3 = 76
