Answer:
The correct answer is "He can sell 96 lots"
Step-by-step explanation:
The developer has 100 acres of land.
He wants to preserve 30% of the land for another project
100 Acres x 30% = 30 acres to preserve
100 acres - 30 acres = 70 acres to sell
1 Acre = 43,560 square feet
70 acres x 43,560 square feet = 3´049,200 square feet
If zoning requires the lots to be at least 31,500 square feet
3´049,200 square feet ÷ 31,500 square feet per lot = 96.8 lots ≈ 96 lots
He can sell 96 lots
