Final answer:
The information provided does not clearly indicate the pricing scheme for owning 7 condos, and thus without additional context or an explicit pricing structure, a conclusive answer cannot be given. The correct multiple-choice option is none of these.
Step-by-step explanation:
To determine how much to charge for someone who owns 7 condos in one building, we need to analyze the provided reference information. Unfortunately, the information given lacks a clear pricing scheme that directly states the cost for owning 7 condos. If we examine the sequences and patterns within the reference, we don't find a consistent formula that includes a per-condo price multiplication or addition. Since no specific rule for scaling up to 7 condos is provided based on the given data, it's impossible to determine the exact charge for 7 condos. Therefore, we cannot confidently choose between options A) $1,200, B) $1,400, C) $1,600, or D) $1,800.
Without additional context or information, such as the charging scheme per condo or any potential discounts for multiple condos, a definite answer cannot be provided. It's essential to consider context when determining prices, particularly in problems related to economic scenarios like this one. The correct multiple-choice option is none of these.
