On three 150-poin tests, you earned grades of 88%, 94% and 90%. The final test is worth 250 points. What percent do you need on the final to earn 93% of the total points on all tests.
What are the steps to solve this?
You would need to get 98% or better on the test in order to average out the other three scores to a 93% in total which would be getting a 245 out of 250 on the final test
