You can put this solution on YOUR website! Professor Zewail counts her midterm as 3/5 of the final grade and the final exam as 2/5 of the grade.
Dale must have a final average of 70 to receive a C or better in the course.
If Dale scored 88 on the mid-term exam, what range of scores on the final exam will give Dale at least a C?
-----
60% of the final grade depends on the midterm
40% of the final grade depends on the final exam
-------
Equation:
(88/100)60 + (x/100)40 >= 70
----
88(3/5) + x(2/5) >= 70
----
88*3 + 2x >= 350
44*3 + x >= 175
x >= 43
---
Ans: 43<= x <=100
