21. The price per square foot of a property is calculated by

Answer: C

Explanation:

The price per square foot of a property is calculated by dividing the sales price of a property by its square footage.

To determine the price per square foot, one must divide the total sales price of the property by its total square footage. This calculation provides a standard metric for evaluating property prices.

A) multiplying the total square footage by the sales price of the property.

This option is incorrect because it suggests that one should multiply the total square footage by the sales price to find the price per square foot. In reality, this calculation would yield the total price of the property, not the price per square foot.

B) calculating the ratio of heated and cooled space to the overall square footage.

While this option discusses a ratio, it does not pertain to calculating the price per square foot. The price per square foot specifically relates to the total sales price divided by the total square footage, not a ratio of specific types of space.

C) dividing the sales price of a property by its square footage.

This option is correct as it directly describes the method for calculating the price per square foot. By dividing the sales price by the square footage, one obtains the cost associated with each square foot of the property.

D) using the total lot size and dividing it into the sales price of the property.

This choice is incorrect because it refers to dividing the sales price by the total lot size, which may include areas that are not part of the living space. The price per square foot should be based on the total square footage of the property, not just the lot size.

Conclusion

The correct method for calculating the price per square foot is to divide the sales price of the property by its square footage, as indicated in Option C. Options A, B, and D fail to provide the appropriate calculation method, leading to misunderstandings about property valuation. Thus, Option C stands as the definitive answer for correctly determining price per square foot.
