You can put this solution on YOUR website!
Let n = number of workers needed to finish job in 45 days
I'll try to get everything in terms of hours.
A 40 hr week is 8 hrs /day, since
40%2F5+=+8
45 days is 45%2A8+=+360 hrs to meet deadline
Each worker needs to work 750%2Fn hrs
I can say that the rate of n workers working together
must equal 1 house done in 360 hrs
n%2F%28750%2Fn%29+=+1%2F360
n+=+750%2F%28360n%29
n%5E2+=+2.0833
n+=+1.443
2 workers are needed. This is just a stab at it.
I'm not sure, and you should get another opinion, too
