Using weighed mean, it is found that the final grade is 64.73.
--------------------------
To find the weighed average, we multiply each grade by it's weight.
--------------------------
Since we want to find the weighed average, we have to identify in the text the grades, and it's respective weighs.
Grade of 71, with a weight of 67%(as it states in the text, the higher grade has a weight of 67%).Grade of 52, with a weight of 33%(as it states in the text, the lower grade has a weight of 33%).Thus, the final grade is:
