Question

A one-way flight from Dallas to Atlanta is "150x − 100" miles. Find a single expression that represents the distance for a round-trip flight.

Answer 1

2 (150x-100)

or

300x-200

Answer 2

300x-200

Step-by-step extplanation:

A round-trip flight means that you travel back and forth to the same place. So, if you have the expression for a one-way flight, you have to multiply it by 2 to get the expression for the round-trip flight:

2(150x-100)

300x-200

The expression that represents the distance for a round-trip flight is 300x-200.
