Final answer:
The correct option cannot be specified. The statement about charging $4 per opening for creative cut mats is subjective to the business's pricing policy. It could be true for some businesses, whereas others may have different pricing strategies for custom-cut mats.
Step-by-step explanation:
The statement that creative cut mats should be charged at $4 per opening in addition to the basic mat price is a policy that could either be true or false depending on the pricing strategy of a specific business. This could be a guideline set by a framing or art supply company regarding how they calculate the cost of custom-cut picture mats. When providing a mat for artwork or pictures, businesses might charge a base price for the mat itself, and then add additional fees for each opening that needs to be cut into the mat. This is similar to how a service might have a base price, with extra charges for additional features or customizations.
