(.25)(94.2) + (.15)(83.6) + (.3)(55.7) = 52.80
(70 percent of grade)
Minimum grade for C=70
Subtract from 70. 70-52.80 =17.20
17.20/(.30) is the lowest final you can get.
=57.3
58 or higher to get at least a C average

First you will choose to take the load of each and every 8th grader interior the international. upload the weights at the same time, then divide by applying the style of 8th graders. the respond supplies you the traditional weight of an 8th grade pupil.

so 70% of your grade is 75.4. Let the rest be x. Overall grade will be
G = 0.70(75.4) + 0.30x
and you want G ≥ 70., so
70 ≤ 52.8 + 0.30x
17.2 ≤ 0.30x
57.3 ≤ x

He would need a 100 to get even close to passing. Anything lower than a 90 isn't completely passing IMO.

(.25)(.942) + (.15)(.836) + (.30)(.557) + (.30)(x) = .70
.528 + .30x = .70
.30x = .172
x = .172 / .30
x = .573333333...
He would need a 57.33% to get at least a 70%.
