Let X be the price of the first commodity, so the price of the second commodity is X - $127.
The cost of purchasing two of them is X + (X - $127) = $827.
Combining like terms, we get X*2 - $127 = $827.
Subtracting $137 from both sides, we get X*2 = $954.
Dividing both sides by 2, we get X = $477.
#### 477
