If you have a fraction, then the denominator (bottom) cannot equal 0, since it is impossible to divide by 0. Take a look at the function below.

If we plugged in 2 for x, we would end up with a denominator of 0, making x = 2 "extraneous."
(you can use this example to answer your question, with the denominator being
x-2...any expression that evaluates to 0 when x = 2 would work)
Answer:
2.39%
Step-by-step explanation:
Given that
99 shares at $55 per share = $5445
150 share at $52 per share = $7800
Hence, total share cost => 5445 + 7800 => $13,245
Therefore, given that the average annual yield is the summation of all the income gotten on investment and dividing the amount by the number of years the money was invested.
With a $1.27 dividend per share, and a total share of 99 + 150 = 249 shares
=> 1.27 * 249 = $316.23
Hence, average annual yield = $316.23 ÷ 13,245
=> 0.0239
=> 2.39%
Therefore, Robert Mastersons' average annual yield is 2.39%
First, solve for the difference between the two prices. That is, $2.79 - $2.86 which is equal to -$0.07. Divide this value by the original price and multiply by 100%. This is shown below,
(-$0.07 / $2.86) x100% = -2.448%
Thus, the percentage decrease is approximately equal to 2.4%.
I don't know if this right but the answer is 26783
