Answer

$280$ minutes or less of monthly phone use, Plan A will cost no more than Plan B.

Steps

Step 1 ：Set up an inequality to represent the situation: $35 + 0.08 m \leq 40.60 + 0.06 m$

Step 2 ：Subtract 0.06m from both sides: $0.02 m \leq 5.60$

Step 3 ：Divide both sides by 0.02: $m \leq 280$

Step 4 ： $280$ minutes or less of monthly phone use, Plan A will cost no more than Plan B.
