Answer:
The median grade would be 89
Step-by-step explanation:
To find the median, first put the numbers all in ascending order.
79, 80, 86, 92, 95, 96
Now isolate the middle term or terms. Since there is an even amount of numbers, we pick the two in the middle. To find the median, we take an average of those terms.
(86 + 92)/2 = 89

By the difference of "5 and a number", I assume you mean that number minus 5. In that case, the expression is 8 times (x-5).
If by "the difference of 5 and a number" you mean 5 minus that number, then the expression is 8 times (5-x).
