Hi. The question is that you have a series of tests that are scored 57, 67, and 60. Tests are worth 80 percent of your grade. Homework counts for 20% and you have a perfect on homework. What does the final test score need to be in order for you to get a 70% in the class?
I first found the average percent of the three tests, which is 61%. I then tried to find the test score to obtain an overall 70% for the tests, and then multiplied it by .80. From here, I don't know what to do. Please help.
thanx
