if i have a 71 c in math and i get 100% on a test worth 14% what is my grade now

To calculate your new grade after getting 100% on a test worth 14%, you need to take into account the weights of your previous grade and the test. Assuming the test is the only factor affecting your grade:

1. Calculate the contribution of your previous grade: 71% * (100% - 14%) = 60.94%
2. Calculate the contribution of the test: 100% * 14% = 14%
3. Add the contributions together: 60.94% + 14% = 74.94%

Therefore, your new grade would be approximately 74.94%, which you can round to 75%.
