Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

Given:

  • Homework Avg: 93
  • Quiz Avg: 84
  • Test Avg: 72
  • Final Exam: 60

and weights Homework at 20%, Quizzes at 30%, Tests at 40%, and the final exam at 10%

=>Jason's class average is:

=  80*20% + 84*30%+74*40%+60*10%

=  80*0.2 + 84*0.3+74*0.4+60*0.1

= 76.8

≈77
