Are My Guestimations Correct?
Okay, for the last hour and a half, I have been surfing the other site, and crunching enough numbers to make my brain explode:headwall
I am wondering about applied salt prices. We only have a couple bids that want a salt bid, so we would be getting 50lb. bagged salt for $14 per bag. Am I correct in charging $25 per bag applied?
Next is application rates-I figure that for my area, it is going to be pretty cold, and believe that application rates will range from 500lbs. per acre to 1000 lbs. per acre. Now, here is where it gets confusing

I took 500/42,673, and it was.011717. That is
.011717 lbs. per sq. ft. and then 1000/42,673 and it was
.023434 lbs. per sq. ft. I then added the two, and divided by two to get the average which was
.0175755 lb. per sq. ft. I then took that times the lot that we are bidding on 58,350 which was
1025.53 lbs. then, divided by 50 to get # of bags which was
20.5 and times our applied bag rate (25/bag) Which was
$512.76 . However, since we would only be salting after we plow, it would be .011717 * 58,350 = 683.68 lbs. of salt. 683.68/50 = 13.67 bags. 13.67 * 25 =
$341.84 . :headwall
Since we would be salting only after we plow, we would probably only need the 500lbs. per acre, right? I am assuming that we would only have to apply more salt than that if it was really cold out. So we shoulc quote the lower price, right? Basically, I am wondering if my price per bag applied is close, and the application rate of the salt is close.
BTW, if it helps, we are bidding the plowing at $490 for 2-6".
Please, if you have any criticism about my numbers, or anything, please tell me, it will really help. Thanks
