I need help figuring out how to do this problem

[From: ] [author: ] [Date: 11-04-29] [Hit: ]
76, and 88 points out of 100 in four projects. What should be his score in the fifth project so that the average of all the projects is at least 83?-let x be the score in fifth project.x=84-so the final average you want is 83 percent, and average is defined as every score added together divided by the total number of scores.......
I know the answer is 84. but idk how to show my work or how id figure it out

"Jason had to submit 5 animations projects as per his syllabus. In the final semesters, he scored 80, 87, 76, and 88 points out of 100 in four projects. What should be his score in the fifth project so that the average of all the projects is at least 83?"

let x be the score in fifth project.
Then(80+87+76+88+x)/5=83
(331+x)/5=83
331+x=415
x=84

-
so the final average you want is 83 percent, and average is defined as every score added together divided by the total number of scores.

83= (80+87+76+88+x)/ (100*5)

x is the unknown score, 100*5 because there will be 500 points total. solve for x

Hope this helped!!

The answer is 84.
Basically you want the average of the 5 numbers to be 83. Which is (80+87+76+88+X)(let x be the score we don’t know) all divided by 5 (because there are 5 scores)=83 (that’s the number we want it to be). Do the basic algebra. The last score is 84

-
80 + 87 + 76 + 88 + x >= 83

(x + 331)/5 >= 83

x + 331 >= 415

x >= 84

-
(80 + 87 + 76 + 88 + x)/5 ≥ 83

331 + x ≥ 415

x ≥ 84
