A. 46% = 1.191
B. x +46 = 1.191
C. 461.191
D. 1.191 +46

B

Step-by-step explanation:

The answer is b because they had x books then added 46 books and now the total is 1191.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

this answer is !
