Grading System Overall grade is based on the standard gradin

Grading System: Overall grade is based on the standard grading scale: 90% = A, 80% = B, 70% = C, 60% = D,

Solution

Code:

%Homework Grade

hw=0;

hw_weight=0.3;

hw=input(\'Enter a grade matrix for homework(row1=earned, row2=maximumpoints\');

total_hw=sum(hw,2);

hw_percent=total_hw(1)./total_hw(2);

total_weighted_hw=hw_percent*hw_weight;

disp(total_weighted_hw);

%Reading Quiz Grade

rq=0;

rq_weight=0.3;

rq=input(\'Enter a grade matrix for reading quiz(row1=earned, row2=maximumpoints\');

total_rq=sum(rq,2);

rq_percent=total_rq(1)./total_rq(2);

total_weighted_rq=rq_percent*rq_weight;

disp(total_weighted_rq);

%Mid-term Grade

mt=0;

mt_weight=0.3;

mt=input(\'Enter a grade matrix for mid term(row1=earned, row2=maximumpoints\');

total_mt=sum(mt,2);

mt_percent=total_mt(1)./total_mt(2);

total_weighted_mt=mt_percent*mt_weight;

disp(total_weighted_mt);

%Final Exam Grade

fe=0;

fe_weight=0.3;

fe=input(\'Enter a grade matrix for final exam(row1=earned, row2=maximumpoints\');

total_fe=sum(fe,2);

fe_percent=total_fe(1)./total_fe(2);

total_weighted_fe=fe_percent*fe_weight;

disp(total_weighted_fe);

%Total Grade

total_grade=100*(total_weighted_fe+total_weighted_mt+total_weighted_rq+total_weighted_hw);

if total_grade>=90

disp(\'Grade=A\');

elseif total_grade<90 && total_grade>=80

disp(\'Grade=B\');

elseif total_grade<80 && total_grade>=70

disp(\'Grade=C\');

elseif total_grade<70 && total_grade>=60

disp(\'Grade=D\');

elseif total_grade<60

disp(\'Grade=F\');
