Question

The grade for the Fin 308 course is determined by the weighted average of the following grade categories:

Midterm exam	35%
Final exam	35%
Quiz	6%
Homework in Connect	14%
Data analysis assignments	10%
Bloomberg BMC (extra credit)	maximum 3 pts

Student X had 65 on the midterm, 90 on the quiz, 85 on Connect homework, 80 on the data analysis assignment and 2 extra point from BMC. If the student wants to get a B, his weighted average needs to be above 80, which would required a minimum score of ________________ for the final exam (round your answer to the nearest one).

Answer 1

let x be the score required in final exam:

	weight	score	weight * score
mid term exam	35%=>0.35	65	22.75
quiz	6%=>0.06	90	5.40
homework in connect	14%=>0.14	85	11.90
data analysis assignment	10%=>0.10	80	8
extra credit assignment		2	2
final exam	35%=>0.35	x	0.35x
		total	50.05+0.35x

since desired weighted average is above 80.

50.05 + 0.35x = 80

=>0.35x = 29.95

=>x = 29.95/0.35

=>85.571429

=>85.6 marks........( if rounded to one decimal place)

or 86 marks...(if rounded to next whole number).
