erica [24]
Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
                                                             = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
                                                             = 10 * 63 dollars
                                                             = 630 dollars
Rate at which each stocks were sold = 35 1/4
                                                             = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
                                                         = 5 * 141 dollars
                                                         = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
                                                                      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".

Simple...

y=x^{2} -9

y= x^{2} -9

It's quite easy to see x^{2} = x^{2}

Thus, any value of x makes the equation true.

Thus, your answer.
