So my scores are 74, 94, 86, and 72. I followed everything to the letter and to get a 90%, I'd need to get at least a 124% on the next test. Does this mean I will have to get two 90% back to back? Im not sure how that works

Thank-you! This really helped me study for a maths exam :)

What if you would like to calculate the number of 100% tests needed to reach a pre-defined average?

Thank you! I had a similar problem for my statistics class and this helped a lot since my readings didn't have an example for it.

Okay, now how do I do that to find the next 2 or n values? Heeeelp

[sippypepsi]

Ok how to hell did you get 450 if 355 divided by 5 multiplied by 5 is 355.

What if 2 test is worth 40%, 40% and the last test is worth 20%.
