Question 380807: Jason had to submit five animation projects as per his syllabus in the final semesters. He scored 88, 72, 85, and 76 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?

You can put this solution on YOUR website!
use the formula for finding the average:
sum/number=average
sum =88+72+85+76+x since you don't know the value of the fifth point, substitute "x"
.
number = 5
average = 83
.
so,
(88+72+85+76+x)/5=83 simplify and solve for "x"
=(321+x)/5=83
=321+x=(83)(5)
321+x =415
x=415-321
x=94
be sure to check your answwer by plugging x = 94 back into the equation
