Explanation:

Step1: Analyze the inequality \(x > 325\)

The inequality \(x>325\) means that when the number of monthly calls \(x\) is greater than \(325\), Plan 1 is more economical.

Step2: Match with the options

Option A says “If the number of calls is more than 325, Plan 1 is more economical” which directly matches the meaning of the inequality \(x > 325\).

Answer:

A. If the number of calls is more than 325, Plan 1 is more economical.
