Questions dealing with the gas price of a transaction.

So as to encourage miners' continued participation in the network, each transaction incurs a transaction fee denominated in gas units. The more complex a transaction, the higher the number of gas units incurred.

gas price is the amount the payer of the transaction fee is willing to pay for each gas unit. Higher gas price encourages more miners to include the transaction in a block, thereby increasing the likelihood that the transaction will be processed quickly.

If you were in line at a gas station, and you let the owner of the gas station know that you were willing to pay $100.00 US for a gallon of gas if they moved you to the front of the line, they would move you to the front of the line. Higher gas price equals faster service.
