The answer is 36.4!!! You just do .7 times 52.
25.7% decrease
not more than 15
52
70
52 is what percent of 76: = 52 / 76 = 0.684211 or 68.42%
If 50 is passing: right now the contribution towards the total grade is (.70)*52, so the total grade = (.70)*52 + (.30)*E [for the final exam grade]. If the target is 50 for the total grade, then 50 = (.70)*52 + (.30)*E, and solve for E = (50 - (.70)*52)/(.30) = 45.3333, so a grade of 46 would put the final grade over 50. By the way, the maximum possible grade of a 100 on the final will result in 66.4 for the total grade.
315% of 52 = 315% * 52 = 3.15 * 52 = 163.8
(34 percent) percent of 52 = 0.1768
Well, 52 percent = 52/100ths = 0.52
95 + 52 + 70 = 217
52/70 = 26/35
80 * 0.65 = 52
