a certain telescope increases the visual range at a particular location from 70 kilometers to 150 kilometers. by what percent is the visual range increased by using the telescope?	Options:
A) 30 % B) 33 1 / 2 % C) 40 % D) 60 % E) 114.28 %
<gadget id="calculator">150 - 70</gadget>
<output>80</output>

<gadget id="calculator">80 / 70</gadget>
<output>8/7 = around 1.142857</output>

<gadget id="calculator">(8/7) * 100</gadget>
<output>800/7 = around 114.285714</output>

<result>E</result>
a certain telescope increases the visual range at a particular location from 70 kilometers to 150 kilometers. by what percent is the visual range increased by using the telescope?
multiply(divide(subtract(150, 70), 70), const_100)
"original visual range = 70 km new visual range = 150 km percent increase in the visual range by using the telescope = ( 150 - 70 ) / 70 * 100 % = 8 / 7 * 100 % = 114.28 % answer e"
