Answer:
Sold together, both parcels would have cost $ 1,354,500.
Step-by-step explanation:
Given that two parcels of land priced at $ 2,100 per acre were purchased, one parcel was 5 acres in size, and the other was 1 square mile in size, to determine how much should these two parcels have cost together the following calculation must be performed:
1 square mile = 640 acres
2100 x 5 + 2100 x 640 = X
10,500 + 1,344,000 = X
1,354,500 = X
Therefore, sold together, both parcels would have cost $ 1,354,500.
