A student's course grade is based on one midterm that counts as 15% of his final grade, one class project that counts as 25% of his final grade, a set of homework assignments that counts as 40% of his final grade, and a final exam that counts as 20% of his final grade. his midterm score is 66, his project score is 90, his homework score is 75, and his final exam score is 66. what is his overall final score?

Step-by-step explanation:

(15÷100 )x  f(final grade) = 66  / 15: 100 x f= 66(x 100)

                                                     15f=66/15

                                                        f=4,4

25:100 x f , 25: 100 x f=90, 25f : 100 =90(x 100)

                                           25f=90

                                         f₂=3,6

40 : 100 x  f , 40: 100 x f=75, 40f : 100=75(x100)

                                              40f=75

                                              f₃=1,875

20 : 100 x  f, 20:100 x f= 20f : 100=66(x100)

                                       20f=66

                                          f₄=3,3,

Overall final score: 4,4+3,6+1,875+3,3

    (15:100)x4,4=0,66

25x100 x3,6=0.9

40x100 x1,875=0,75

20x 100 x 3.3=0,66

(0,66+0.90+0.75+0.66)x 100=297
