10 Points to figure out my grade....It's got percentages...Can you do it?!?

Question

I'll give anyone 10 points to figure this sh*t out...

So...
Assignment: Percentage of Grade:

Three Quizzes 40%
Final Exam 40%
Group Project 10%
Library Proj. 1 2.5%
Library Proj. 2 2.5%
Individual Proj. 5%
Total 100%
PercentageFinal Grade
93 – 100A
89 – 92A–
85 – 88B+
81 – 84B
77 – 80B–
73 – 76C+
69 – 72C
65 – 68C–
61 – 64D+
57 – 60D
53 – 56D–
below 53F

So I got a...

20, 22, and 19 (Each out of 25) on the three quizzes (40% of grade)

40/50 on the Final (40% of grade)

100/100 on Grade Project (10% of grade)

9/10 on Library Project 1 (2.5% of grade)

9/10 on Library Project 2 (2.5% of grade)

and a 100/100 on Individual Project (5% of grade)

More points to anyone that explains how to do this (the percentage of grade thing throws me off)

Damn...it is an 84....

Okay 5 people got it right....and all of the explanations sound right...sooo...


I'll pick a number 1-10, and with only one guess, the person closest gets the 10 points....GO!

Answer 1

did it all on my calculator so not gonna show the work, but you have a 84.0333% or basically a high B.

oops just realized that you asked how to do it. k ill explain

just do each part one by one

for example:

you got a 20, 22, and 19 on your quizzes.
add them all together and you have a 61 out of 75
that is a 81.33333%. since that is 40% of your grade, multiply it by .4 and you get 32.533333%

that number that i just got is the score you got on 40% of your grade. in other words, out of the 40% of the grade that is comprised of quiz scored, you got a 32.53333%. if you do this for all of them, you add up each piece and you get your final percentage.

here are a few more if you didnt understand:

40/50 on final
thats 80%
so you got an 80% on 40% of your grade.
80% of 40 is 32. therefore, you got 32% on the 40% of your grade comprised of the final

grade project you got the full 10%

library projects you got 18/20 on 5% of your grade
18/20 is 90%
90% of 5 is 4.5
thus you got 4.5% on the part of your grade comprised of library projects

lastly, the individual project
you got the full 5%

so add up my final number for each part

32.53333% + 32 + 10 + 4.5 + 5

that equals 84.0333%

therefore a B

hope i kinda helped lol

Answer 2

Quizzes:
1) 20/25 = .8 * 100 = 80%
2) 22/25 = .88*100 = 88%
3) 19/25 = .75*100 = 76%
Now take the average: 80% + 88% + 76% = 244% / 3 = 81.333%
Now multiply the average percent by the percent of your total grade: 81.333% * 40% = 32.53%

Final:
40/50 = .80*100 = 80%
80% * percent of total grade (40%) = 32%

Grade Project
100/100 = 1 * 100 = 100%
100% * 10% of total grade = 10%

Library projects
9/10 = .9 * 100 = 90%
90% * 2.5% of final grade = 2.25% each
Since the grades were the same, double that: 4.5%

Individual project
100/100 = 1 * 100 = 100%
100% * 5% of final grade = 5%

Now add up all those percentages
-----------
32.53 + 32 + 10 + 4.5 + 5
And your final total percentage is 84.03%
So you got a B

Answer 3

You need to convert all your grades on assignments into fractions of 100 then weight them according to how your teacher instructed them to be weighted and then sum the weighted numbers:

Quizzes: 61/75 = 81.33*.40 = 32.53
Final: 40/50 = 80*.40 = 32
Grade Project: 100/100 = 100*.10 = 10
Library Project 1: 9/10 = 90*.025 = 2.25
Library Project 2: 9/10 = 90*.025 = 2.25
Individual Project: 100/100 = 100*.05 = 5

32.53 + 32 + 10 + 2.25 + 2.25 + 5 = 84.03%

You got a B.

Answer 4

Mathmatically, you got an 84.03%, so probably a "B"

Here is how I did it:
you got 61 points out of 75 for quizzes. That is 0.813 (as decimal) times 40% of your final grade gives you 32.53%.

Now do that for each part.

40/50 (or 0.80) of 40% = 32%

100/100 (or 1.0) of 10% = 10%

9/10 (or 0.90) of 2.5% = 2.25%

9/10 (or 0.90) of 2.5% = 2.25%

100/100 (or 1.0) of 5% = 5%

Now add them all up: 32.53% + 32% + 10% + 2.25% + 2.25% + 5% = 84.03%

Good Score, keep up the good work.

Answer 5

Multiply the percentages by the manstromical unit (the number of times you got that percent). Add it all. Count the numbers of grades you got at all. Divide the sum by the number of grades ; thats your average. A rough estimate is 97. Grades (such as a+ or B- vary to the school system your school uses.
I would say A to A-. Maybe even an A+ if your teachers cut you some slack.

Answer 6

92.8 ... likely an A .. congratulations

Everyone else's answer is much lower .. so will show my work (and maybe discover my error)

[(20+22+19)/75]*.4 = 32.5
(40/50)*.4 = 32
100% = 10
[(90/100)*2.5]= 2.25
[(90/100)*2.5]= 2.25
100% = 5
Total = 84 .. opps I made a boo-boo earlier .. sorry. A nice solid B

Answer 7

your avg. is an 84 B. your quizzes avg. out to 81.3 multiply by .4=32.4 your final 80*.4=32 your individual project 100*.05=5 90*.05=4.5 100*.1=10 add 32.4 +32+5+4.5+10=83.9

Answer 8

84.02% overall

You got 61 out of 75 for the quizzes. ..which is 81.3 * .40= 32.5
You got 40 out of 50 for the Final....which is 80* .40=32
You got 100 out of 100 for the Project.....10
You got 9 out of 10 for the Project...which is 90*.025=2.25
You got 9 out of 10 for the Project...which is 90*.025=2.25
You got 100 out of 100 of the Project....5

so...32.5+32+10+2.25+2.25+5=84.02
