Explanation:
The question is asking for an expression to calculate the course grade based on the provided information. The teacher calculates the course grade by adding four semester grades, which are 91, 92, 93, and 94. Then, the teacher adds six times the final grade, denoted as 'f'. Lastly, the teacher divides the total by 10.
