Answer:

$w>48$ pounds

Step-by-step explanation:

The customer will be charged extra if the weight of their suitcase is above 48 pounds.

Let the weight of the suitcase = w (in pounds)

Therefore, w above (greater than) 48 pounds is written mathematically as:

$w>48$ pounds

This is the inequality that represents w, the weight of the suitcase in pounds, that will have an extra charge.
