Final answer:
Mary Rose will pay a total of $30,000 for the North half of the Southwest quarter of the Southwest quarter of Section 7, which is 20 acres at $1,500 per acre.
Step-by-step explanation:
Mary Rose plans to buy the North half of the Southwest quarter of the Southwest quarter of Section 7. To determine how much she will pay for the parcel, we must first calculate the total number of acres in that specific portion of land.
A section is one square mile or 640 acres. The Southwest quarter of a section is one-fourth of this total, which is 160 acres. The Southwest quarter of that quarter section is again one-fourth, resulting in 40 acres, and half of that is 20 acres. Since Mary Rose wants to pay $1,500 per acre, we calculate the cost by multiplying the number of acres by the price per acre.
Therefore, the total cost is 20 acres × $1,500 per acre = $30,000.
