The percentages to the left equal to 100%. So, based on the grade numbers to the right, what is the final average grade in TOTAL?
25% = 80%
25% = 85%
25% = 80%
10% = 78%
10% = 100%
5% = 96.89%
Thanks!!!!!

Multiply each score by the weight, then add the results and multiply by 100
(.80 * .25) = .2
(.85 * .25) = .2125
(.80 * .25) = .2
(.78 * .10) = .078
(1 * .10) = .1
(.9689 * .05) = .048445
Total = .838945 * 100 = 83.8945

Add the six percentages up and then divide by 6.

there is no average really: 20 + 21.25 + 20 + 7.8 + 10 + 4.8445
83.8945
