Abroker has a problem of subdividing a 10 acre tract into 50 by 100 foot lots; after allowing 85,600 square feet for the necessary streets, how many lots will the broker realize from this subdivision?

There are 944 lots the broker will realize from this subdivision.

Step-by-step explanation:

Since we have given that

For 10 acre tract,

Number of lots = 50 by 100 foot = 5000

If the tract has 85600 square feet, we need to find the number of lots.

Since 1 acre = 43560 square feet

so, 10 acres = square feet

Since there is direct variation, so it becomes,

Hence, there are 944 lots the broker will realize from this subdivision.

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
