## Comment on

Two Unknown Values## i can't understand why its

## Let's keep going from where

Let's keep going from where we have: x + y = (6.25)(8)

Evaluate to get: x + y = 50

Now that we know the sum is 50, how can we determine which value (x or y) is greater?

Consider these two case...

case i) x = 1 and y = 49 (this satisfies the condition that x + y = 50)

In this case, Quantity A is greater than Quantity B

case ii) x = 40 and y = 10 (this satisfies the condition that x + y = 50)

In this case, Quantity B is greater than Quantity A

Answer: D

Does that help?

Cheers,
