Final answer:
A modifier does not always affect the price of a charge.
Step-by-step explanation:
A modifier always affects the price of a charge. This statement is false. The price of a charge can be affected by various factors, and modifiers do not always impact the price. Some modifiers, like discounts or promotions, can lower the price of a charge, while others may not have any effect on the price at all. The impact of a modifier on the price depends on the specific circumstances and context.
