A residential zoning category requires at least 12,500 square feet per lot. The developer is reserving 35% of the land to streets, sidewalks, a park, and a community center. The tract of land for development consists of 160 acres. How many residential lots are available for development?

It will have available space for 326 lots of 12,500 square feet

Explanation:

The land available is 160 acres

from which 35% will be reserved for streets, sidewalks, a park, and a community center

So land available for the lots:

160 x (1 - 0.35) = 160 x 0.65 = 104 acres

1 acre = 43560

104 acres x 43,560 = 4,530,240 square foot available

4,530,240 / 12,500 = 362.4192 = 362

We round down, because we can only sale complete lot
