Question 929118: An average of 80 is needed to obtain a grade of B in this course.
Suppose your grades on the first three tests are 83, 78, and 75, and your class participation grade is a 76. What minimum score do you need on the 4th test to have a B average? Can you get an A average? Why?

You need an 84 on the 4th test for your *test* average to be a B (solve (83+78+75+x)/4 = 80). However with class participation, we do not know since this depends on the weighing of class participation.
