Answer 1

Answer:

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
