Answer 1

64.66

Explanation:

Given,

a=100%

b=3

c=-4

d=9

e=3

f=5

g=3

h=-1

To find x,

a = bx + c + d + ex + f +gx + h

100 = 3x - 4 + 9 +3x + 5 + 3x - 1

100 = 9x + 9

91 = 9x

91/9 = x

x = 10.11

The students who don't like RED are,

ex + f + gx +h

= 3(10.11) + 5 + 3(10.11) - 1

= 60.66 + 4

= 64.66
