If my final math exam is 10% of my grade and my average is a 74 and i made a 68 on the test what is my final grade ?

Answer 1

The average before the final was 74. That is 90% of the grade and the 68 on the final is 10%.

Add 9 * 74 plus 68 = 734. Divide by 10.

Final net grade is 73.4

Answer 2

Madison,

Given: Average grade before the final exam(worth 90%) = 74%

Final exam(10% of the final grade) = 68%

Final Grade = (90% of 74%) + (10% of 68%)

= (0.9)(0.74) + (0.1)(0.68)

= 0.666 + 0.068

= 0.734

= 73.4%
