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
