Quantity A |
Quantity B |
The resulting rate of data transfer if the bandwidth is quadrupled and the number of networked computers is more than tripled |
\(\frac{4}{9} \times r\) |
A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.

Column A can be written as \(\frac{4b}{9^+ n^2}\), where \(\frac{b}{n^2} = r\). Then, we have the same quantity in the two columns but for the denominator, which in column A, is \(n^2\) multiplied by a number there is greater than 9 (since we are more than tripling), even if it was 9.0001, column B would be greater.
