Answer: Option (A)
Step-by-step explanation:
Let the original price of the clock be "x
"
<em>The clock is then resold to a collector = x + 20% of "x
"</em>
<em>= x + 0.2x</em>
<em>= 1.2x</em>
Now, the shop re-buy the clock at a price = <em>
</em>
<em>
</em>
<em>= 0.6x
</em>
Therefore,
<em>Original Cost - Buy-Back price = $100</em>
<em>⇒ x - 0.6x = 100</em>
<em>⇒ x = 250 </em>
Hence , the selling price of the clock for the second time is
<em>
</em>
<em>= $270
</em>
<em></em>
Use the distance formula!
d = square root of (x2-x1)^2 + (y2-y1)^2
=19.4165
I say B quantity to figure out the value in the data
Hope this helps!!

Unfortunately your response would only be true if CD was perpendicular to AB. However we don't know if CD is perpendicular or not. So we don't have enough information. The actual answer is choice E) None of these.
