on 3 tests you earned grades of 88%,94%,and 90%. Each test was worth 150points. The final exam is worth 250 points. How many points do u need on the final exam to earn 93% of the total points on tests? What percent do you need on the final?

Answer 1

Let's figure the total number of points you've earned.

0.88 * 150 = 132
0.94 * 150 = 141
0.9 * 150 = 135

Total points = 408

450 + 250 = 700 points possible

0.93 * 700 = 651 points you need to have an over all average of 93%

651 - 408 = 243 points needed on the final exam

Answer 2

243/250 = 97.2% needed on final exam
