Answer:

Choice B) 50

Step-by-step explanation:

[tex]\frac{12}{x}[/tex] = [tex]\frac{24}{100}[/tex]

cross multiply

24x = 1200

x = 50

OR you can do the following

Let n = missing number

12 x 2 = 24

15 x 2 = 30

17 x 2 = 34

23 x 2 = 46

n x 2 = 100

57 x 2 = 114

--

n x 2 = 100

Divide 2 from both sides

n = 50
