A bar over a sequence of digits in a decimal indicates that the sequence repeats indefinitely. What is the value of (10^4 -10^2)(0.0019)?	Pick:
A) 25 B) 20 C) 21 D) 18.81 E) 22
You get 10^2 (100-1) (.0019)   we know   19/10000= 
<gadget id="calculator">  19/10000</gadget>
<output>19/10_000 = around 0.0019</output>
.0019   10^2 (99) * (19/10000)   10^2= 100 and 100^2 = 10000   Cancel out the 100 with the 10^2   Left with 99(19/100).   0.99*19= 
<gadget id="calculator">0.99*19</gadget>
<output>18.81</output>
18.81   Answer : 18.81
