To determine the inequality that represents the situation where Company A costs more than Company B, we need to compare the total costs of both companies.
Let \( b \) represent the number of brochures.
-
The cost for Company A is given by: \[ \text{Cost of Company A} = 25 + 0.20b \]
-
The cost for Company B is given by: \[ \text{Cost of Company B} = 0.30b \]
We want to find the condition where Company A's cost is greater than Company B's cost: \[ 25 + 0.20b > 0.30b \]
This simplifies to the inequality we are looking for.
So the correct answer is: $25 + 0.20b > 0.30b$
