Answer:

Step-by-step explanation:

The average of an
amount of values is equal to the sum of all the values divided by
. Thus, for any five scores to have an average score of 85, the sum of the scores must be
$85\cdot 5=425$

Therefore, we have the following equation:

$73+84+91+78+m=425,\\m=\boxed{99}$
